I’m in the heavy construction industry. I got on board with this channel during the Orville dam reports. This aviation guy was spot on in that field. Now when he is in his element and I’m out of mine, I trust him.
Sorry to hear you have been grounded due to PSA out of tolerance. I am an 11 years prostate cancer survivor. I wish you well in regaining you classification where you will be able to fly again. from Texas
Same here, Richard. Agent Orange exposure, prostate cancer, I elected to robotic-assisted surgery 9 years ago and PSAs have been zero since. Hoping Juan's treatments lead to the same results.
Hi Juan. I am a Pratt & Whitney budget manager for our Airbus NEO program. I really enjoy your videos . You are well informed and do a great job with your channel. I will keep you in my prayers . I have to put together a 10 engine development program this week for whatever this NMA will be. My dad has prostate cancer and has done well . You will too . Take care my friend and thank you for the update. It’s a shame what’s happened with the MAX. Lithium Ion Batteries didn’t kill over 300 people with the 787. I think Boeing should cut their losses with the MAX and focus on a new airframe with better transparency during its development and FAA certification. Peace out brother 👍
Best aviation guy on the web. As a mechanical engineer and occasional pilot for 5 decades, and an A&P for 3, I really appreciate your very knowledgeable and easy-to-follow insights. Hope you're back in the air soon.
I'm one of your "new" subs from the Oroville Dam coverage. From a lay perspective, I think you've done an outstanding job explaining these aviation issues in a way that's understandable, and without snootiness that makes a lay person feel ignorant. Thank you for that. Oh and I love the cameos with the children, they crack me up!
I am a doctor in San Francisco my partner went to a lecture in the city given by the man who invented the PSA test ...he assured everyone in the audience that that particular test should not be used to make prostate health care decisions. It is antiquated and unreliable you should find information to substantiate this and presented it in support of your case. Like your shows.
Cyrus Thomas DC Now that is a substantial comment. The public has no recourse but to trust the test given fir PSA. Like most treatments, we are at a loss to know the best options to ask for. Hell, we are at the mercy of being prescribed medicine. Good to know this. Although it won’t fix Juan’s problem now, he will just have to wait the six. Thanks for the Dr perspective.
You should be careful not to complicate an already controversial situation on the basis that you are 'a doctor'. I am too. The PSA position is nuanced - exactly not the sort of thing that a public eager for certainty needs to get more confused about. How Americans laughed and laughed at us fuddy-duddy, primitive Brits who were so very reluctant to implement this cutting edge tech except in very careful defined cases. My American B-i-L used to fly back to NC to get his PSA checked rather than being 'murdered' over here because his case wasn't thought 'appropriate' for testing. PSA is neither 'antiquated' nor 'unreliable; it's just very non-specific; useless for the routine detection of most cases of prostate ca. Post diagnosis and treatment it's reassuring if levels remain very low, bad news if they've shot up to very elevated - and pretty unhelpful if they're somewhere in between. It's not a go/no-go test for recovery or recurrence and it's uncritical use has left armies of men worldwide in a post-treatment limbo. The key to using PSA properly for individual patients is to measure it regularly and look at the trend.
Hang in there, Juan. One of my friends is a Delta Captain who has beaten cancer TWICE and gotten back into the left seat. He had a rare form of tumor in his neck. Survival itself was threatened, quite apart from the flight physical. It was a struggle, but he won. On a subsequent re-check, a small nodule was found on a lung. It was removed, found to be malignant but completely resected. Once again, he got his medical back. He's considerng retirement now, on HIS schedule, by HIS choice. He knows how blessed he's been. As a fellow customer of the PSA test, I am rooting for you. Thanks for these outstanding updates; keep them coming.
As a fellow pilot, you provide a great service to all aviators and non-aviators alike. We’re rooting for you Juan, please provide us content for many years to come.
95K subscribers -- WOW! I got in at 5K if I remember correctly. Congratulations. Please get well and flying again, but in the meanwhile you have time to make more videos.
@@alabas4570 👍 Spot on. I've only been a subscriber for about a month. I must say, I have thoroughly enjoyed each episode I've watched. Thank you Juan, for sharing your knowledge of aviation with us. I don't fly very often but, when we take another trip, I want the Captain to be just like you. Thanks again. Stan
I really like your candor. You have a way of talking as if I'm the only one in a room when you've got tons of listeners. You're great human being. We struggle to live. I've been watching your MCAS updates & you're on spot. SUPERB. About time you had another update. You'll be flying again, soon. Lots of folks counting on you. BRAVO!
@Steve Wright the last Steve Wright, that I knew that faced a cancer issue principly with affirmations passed away in 6 mo. Many cancer modalities are in the western diet but most have a nutritional solution. See utube channel nutritionfacts.org & search for your issue. Small study of 23 prostate surgery candidates were requested only to add 3tbls ground flax seeds daily. 3weeks later only 1 required surgery. 18 eventually stopped related meds completely. See book "China study"(nutritional) for solutions for Heart disease, diabetes, etc.etc. found in western diets.
I'm not an aviator, but your explanations are remarkably clear and understandable. I especially appreciate you're objectivity. I've learned more about this entire problem from your videos than any other source. Finding a trustworthy source of information on the internet is always appreciated.
It always amazes me when I listen to one of Juan's reports that mainstream media seem totally incapable of offering this sort of in-depth explanation of a subject, I find it completely fascinating, and I can see from 9k subscribers I'm not the only one! Keep doing what you're doing Juan, and I just hope more mainstream media is watching and taking notes.
You are the best channel I've yet found explaining the details of engineering disasters that the media is frankly too clueless to do. Please stay in good health, the intelligent population needs people like you around to do this kind of thing.
Nothing like getting here early. Juan, you're so very knowledgeable, but your shyness and humble way make learning a breeze. I absolutely love that you make GOOD videos, but don't edit the heck out of them...mistakes stay and I love it.
@blancolirio You criticize Boeing for rushing the design (even though that is not true) but say of the mistakes in your own work, "Time is of the essence, not production quality." ?!! How's that for hypocrisy?
Good luck getting your Class I Medical back. As a retired airline pilot I've known several colleagues who have had prostate cancer and eventually got flying again. I really enjoy your videos.
Juan, I can see why this presentation felt so long to you; because you took a massive multifaceted subject and painstakingly edited it down to a concise easy to understand narrative that blows away the lamestream media's presentations on the subject. Kudos!! Nice to see you getting the recognition you deserve, come on 100k. We're all proud of you!
I'm an aviation enthusiast, and a video of yours showed up on my RU-vid suggestions, and I've been hooked. I enjoy DJ's for the economics, fleet changes and purchases. I enjoy this channel for the technical aspects. Hope you're recovering quickly.
Great video. I just got off the 737 six months ago and am now flying the 777. I have also been keeping informed about the Max saga as it unfolds. I read the 8 page article in Aviation Week & Space Technology today on the Max saga. Your video is far more informative than what AWST published. I also enjoyed your videos about Oroville Dam. Thanks for the quality videos!
Thanks for further clarifying the process that led to this disaster. It still sends a chill down my spine when reminded of the elevator override capability that MCAS ended up with.... the crew had no clue.
You are a breath of fresh air, Juan. Your no-bullshit explanations and increasingly detailed analysis of the whole saga is amazing. I've been building a very expensive 737 MAX 8 flight simulator since last year, before the crap hit the fan. I've followed all of the reports and info, but none come close to the unbiased stuff that I get here. I've since stopped looking for any news elsewhere and just rely on your updates for all the latest news. I know that Boeing and the MAX will recover from this disaster and Boeing will learn a lot of very expensive lessons. Take care and good luck with the PSA's.
Thank you for yet another crystal clear, thorough, concise and articulate overview of a complex and sensitive situation. Wishing you a speedy return to flying.
I watched all the way through this because Blancoliro is the only one who I stare at for the worth of such vital information, such a sincere compelling individual.
Well, you brought the whole story together here for me with this video, and the length was necessary to link the whole saga together. Being a retired airline pilot, I have had no problem following your earlier videos and the technical terms therein. Much of the puzzle was unknown to me, but you made it all make sense with the additional information here. My own career was almost all old technology airplanes with only the A300-600 being new glass cockpit technology, and I personally did not care for it much. To each his own, I guess. Of course, the problem the MCAS was meant to correct does not really have anything to do with glass or old style gauges, but is an aerodynamic problem. Many airplanes have had problems along the same lines, and usually the choice has been made to use a hardware fix rather than a computer software solution, the Boeing 767 pitch stability problem in the landing configuration being fixed with vortex generators was one of them. That type of fix does away with the software fix problem requiring abnormal checklist procedures in the QRH to overcome a failure such as in the AOA indicators and the software and a lack of redundancy for such an occurrence as happened in these two accidents. Of course, there was no such inclusion of any procedures in the QRH, further making this MCAS solution unacceptable. I am now horrified that Boeing thought that what they came up with was fine and adequate, and I can not believe that they actually thought that there was nothing to it that line pilots could not handle without any prior knowledge of its existence! I question what failure mode testing of it was done by their own highly skilled test pilots with engineering backgrounds where they also thought that no training or even mention of the system was necessary for the average line pilots to safely handle a malfunction. My confidence in Boeing has been badly shaken by this, but I think (and hope) this may cause a big change in how things are done in the future. I'll add here now as an edit that it seems odd that those two knowledgeable FAA Certification Inspectors chose to leave and maybe seek their fortunes elsewhere in or out of the industry, and then Boeing added a whole bunch more to the MCAS software when the two less experienced inspectors showed up to take their places. It's probably a coincidence, but maybe not...... Who knows?
Thanks Juan for this comprehensive update. We appreciate your in-depth, yet understandable, reviews of these aircraft incidents. Praying for your return to excellent health and the cockpit!
I appreciate your excellent point of view on the 737 MAX and the other updates on the different incidents or accidents on airplanes. This gives people insight of what happened and the construction of airplanes and knowledge that aircraft is much safer transport than the media gives you in case of incidents.
Great in-depth discussion of the MCAS saga on the 737 Max. I really enjoy your ability to relay topics and information situationally and in context. You are definitely a teacher. It’s like the von Steuben quote about “...this is why you do this, and he does it.” I don’t fly, but I was around our local airport and a few experienced pilots as a kid. I always found them to have, like you, an encyclopedic knowledge of airplanes and the engineering that went into them. They loved to talk shop, and I loved to listen. This channel, you sir and the information you present is really a breath of fresh air in the “look at what I’m doing” RU-vid space today. Just keep doing it Juan. Thank you for the content and information sharing.
Love the Luscombe 8F, had one when we got married 63~ years ago, sold it to build our first house. While I hung up my goggles five years ago (I'm now 90) I still get to fly with a friend who owns a beautiful 8F with an 0-200A engine. Love your channel and am a bell subscriber.
Wow! I am always impressed with your reporting/updates. They are so full of information, and explained so that even a guy as thick headed as myself can understand it. In each of your reports I have noted that, aside from hearing the passion, I can see and feel the passion in your voice as you explain this whole "737-Max" mess. I also sense the frustration. It has been a joyful experience watching all of these reports. I even get "fired-up" hearing that passion. I know I am not alone in these observations. I understand the FAA on not allowing you to fly the big planes. I hate like hell to hear that they won't let you fly your "Mighty Luscomb"... That has to be pretty depressing. Thoughts and prayers for you my friend...
Your explanation of the 737-MAX accidents is the very best. Thanks so much. As a former Beechcraft Travelair pilot with IR ratings, I hope non-pilots understood as well. Dave in Phoenix Arizona USA
An absolutely amazing & comprehensive update presentation on this topic. You have again left us breathless with your depth of knowledge for the subject matter. Thanks JB!
Another outstanding explanation of a complicated topic. Great job, Juan. Your prostate issue is a tough deal, hope you get cleared at the earliest possible time.
Yours is the only readily available media source for the layperson to gain an understanding of the intricacies of the engineering and human input involved in creating and operation of these Marvel's of the modern world. You do it all without talk down to viewers allowing that we do have a capacity for understanding a little physics, logic, mechanical design and human interfaces and input in their function and operation. Many thanks Mr Brown you make one fell as if we too can be "in the loop", lol. I always look forward to your next iteration. God bless good health and safety to you and your family.
Juan, thank you so much for the explanation of your channel name. I have been all over google trying to find the meaning, but with no good results. Even considered a message to you. Love all your videos, don't comment much. Hoping for your fast recovery and back in the pilot's seat. You're the only airline pilot that I know so gotta get you flying again! Pulling for you brother!
"Man that was a long one!" Considering the amount of ground covered I thought it was remarkably concise. By far the best and most detailed analysis out there in the public domain, clearly showing how multiple minor failures, often over a considerable period of time, can add up to a major accident. Or two. I'm just a PPL but the Swiss cheese model (all the holes lining up and you fall through) was drummed into me as a student. It's served me well. Thanks Juan, Hope you're getting some flying in the mighty Luscombe with a "safety" pilot.
The Luscombe is pretty small, more a 'one and a half' person aircraft. Juan just posted that he flew as co-pilot in a Bonanza, which is more appropriate.
Excellent content, as always. I, and every other 737 driver, have asked ourselves how we would have performed in those two tragic events. In the beginning, it was not unusual to hear my colleagues (ok, me too) make critical judgments about the competence of those pilots and their seeming inability to kill the stab trim. As we have thought this through, however, I think most of us have become less critical. You hit on precisely why: the disconnect between the usual findings of runaway trim versus the confusing panel indications they were receiving. Thoughtful presentations like yours help to offset garbled media content as well as the mindless pontifications of armchair pilots and various other know-it-alls.
Sorry to hear you are grounded, hopefully only a short while. Thanks for your ongoing technical description of the 737 Max problem. Nice getting accurate information from a pilot's perspective.
Very good accurate informative explanation and great overview of the issue time line. By far the best summary and explanation I have ever heard. It is fairly common that making a well engineered change to make things better often creates unanticipated new issues, often because a seemingly minor change is not fully vetted/tested/commissioned (I comision data centers and this occurs fairly often) under all conditions.
Excellent and comprehensive report from the best and most trustworthy channel. Thank you, Juan. Sorry to hear about your grounding, that is tough and I hope you get your licence back soon. Best wishes.
Hi Juan! Another classic Juan Brown educational experience by the Jedi Knight of instructing. Keep up the good work and best wishes for a swift complete recovery with your health situation.
Another amazing video Juan! You truly are a Renaissance Man ! The ability to explain such complex concepts ranging from dam design to aircraft flight control feel and handling to the average person is a rare gift ! I’m a recipient of this gift and I humbly thank you for the benefit of your knowledge and experience ! Prayers and best wishes for a rapid recovery and return to the captain’s seat ! 👏👏👏👌
Juan an exec excellent report. You provided a historical overview, which I believe helped to understand the chain of events that lead to this mess. Thanks for the great reporting.
Sorry to hear about your being grounded due to health concerns. Praying for your speedy recovery and return to the cockpit. I’m sure you will make great use of your time. Thanks for the highly informative video on the 737 Max situation. You make it very clear and understandable to the non-aviator.
The Ethiopian Airlines incident rocked me because I fly with them often around Africa. I was never entirely clear on what went wrong. Many many thanks for this fantastic detailed clear and understandable explanation of the cause and what is being done to resolve it. Much appreciated. Greetings from Cape Town.
Been watching blancolirio channel for a long while. Tops my "Recommended" List quite often. Somehow, just never clicked on SUBSCRIBE. So, here goes. I'm a former, long time ago, USAF & Braniff Pilot. Went on to retire from the FAA. I've been intrigued by aircraft accidents since the "It's a Big Sky" accident over the Grand Canyon. All are learning experiences. Best wishes for getting that 1st Class back.
Amazing educational video that we can get nowhere else. I love the way you present information (clearly and concisely). It makes it easier to learn and understand. Thanks for all your efforts Juan, and hopefully you are back flying soon.
I am a retired pilot. USAF, civilian, 6 airlines, a year as a Boeing flight test engineer. MS Aero/ Astro. I've flown most of the jet Boeings (Not the B-47, B-767 787, or 777) and retired flying the A-330. I did not care for the Airbus design philosophy. The Airbus airplane "feel" is like a 1990 computer game control stick connected to an old 286 processor via a bungee chord. I have to admit it was fun watching a new copilot fight the gusty crosswinds in Tokyo.
Hey Juan, you have sooooo many supporters here! Yes we do love your humbleness and then some. My little girl, age 10, went through 2 cancer scares and made it through. Am glad it is 2019 given the treatment modalities available today. I made a decision many years ago to not have children due to a horrible genetic disease. I adopted my little girl when she was 2.5 years old. Because of her "color" no one would adopt her. She survived 2 bouts if cancer. You will sail through this...or should I say, fly through this. Hey, you are going NO WHERE but here on this wonderful earth! P.S. I know it six not working for 6 months. Yikes! But please keep your vids coming. Thank u!
Great explanation of how the MCAS system was designed to work and actually worked. Thanks for your time, skill, and knowledge. I really enjoy for videos.
Thank you Juan. I’m not a pilot but by watching your channel I have learned a lot as usual. I started watching during the Orville Emergency and have been hocked ever since. You are also in my prayers daily. Keep up the great reporting 👍
Wow, thank you for making this video. Best video on failure mode and fix to date, +100 for including branch diagrams. Wishing you a speedy recovery as well
Thank you - that was an exceptionally clear explanation. I'm not a pilot but have a good understanding of aerodynamics and systems so the explanation was crystal clear. My sympathies with the PSA watching: as a cancer survivor of 9 years (and counting ) I'm tested every 6 months. Results going down , but it's still nerve wracking at times ! . Good luck and get back in the air soon.
Again, thank you Juan for the educational videos. Now it is more clear to me the issue with the 737-Max. I made a comment a couple of days ago where I said I am an aviation enthusiast, but I am a doctor by training. I am sorry to hear you are dealing right now with prostate cancer, and I wish you a full recovery. What surprises me is how a blood level of PSA could be used by any agency to determine one’s ability to fly? It is a good (not a perfect) marker to monitor the disease after treatment, but to be used as a parameter to have a valid license for flying??? It beats me. I am sure you can perfectly fly as you are right now. Sometimes make agencies go to extremes!! By the way, as a side note for all men reading this note, FYI: it is believed that if all men live long enough, 100% would get some form of prostate cancer in their life! Prostate cancer, particularly the one diagnosed after 65 seems to be associated to aging-related atrophic changes in the gland. And the patient ultimately will die of any other cause (heart, stroke, etc) than from prostate cancer!
How did I miss cancer? Sorry to hear that, but glad you are out of the woods. Can't believe you're about to hit 100k. Found you back when the spillway started falling apart. Love your in depth physics based REAL news.
Thanks for clearing a path through the mire of information/disinformation coming to the surface and in so doing, letting us understand the overall picture more clearly
I appreciate the pilot's explanation of MCAS and the two crashes, and the description of how the design came to be is especially interesting. We are blessed, and sometimes cursed, by automated systems, but behind every one are people that sometimes make mistakes.
Ha Ha - Juan the mindreader! After being a subscriber for months and wondering about the name of your channel, I googled the meaning of blancolirio right before watching THIS upload, and hence was totally amazed that you explained it at the end.
Awesome explanation for pilots and engineers. As a pilot I've found your videos absolutely necessary for me to understand enough to explain the MCAS problem to lay persons. It's up to us pilots and engineers who need to decipher your videos. Yes of course there are some laypersons intelligent enough to get the idea, but unless they flown airplanes, or designed them, it hard to understand as a lay person IMO. Thanks again Juan.
Wow Juan, that was quite an explanation! I've been watching your videos off and on. It's time for me to hit the subscribe button. Thanks for explaining the meaning of your channel name. Ive actually been wondering about that.
Once again.. EXCELLENT explanations and background information giving the 'average Joe' a much clearer picture of this complex issue. I feel like I learn something with every video. Great job!
Hello Juan, Empathize with your condition completely. Finished my nine weeks of radiation about 10 months ago. Didn’t need any lupron (chemo). Two post radiation PSAs so far have registered what is expected of successful treatment. I’m getting there, but seems like it’s taking forever. Sincerely hope you recover completely and are cleared to resume flying. Soon. I’m sure you’ll agree, it is a pain being grounded for this when you otherwise feel fine. I wish you the best and hope you’re flying again soon. My best wishes and thoughts for you.
Excellent!! An in depth explanation. I had to stop it a couple times to look at the displays and try to understand what was happening as it was a bit fast, but followed along intensely. Thankyou!!
Praying for your recovery and a quick return to flying. As always very much appreciate how you honestly report. It is obvious that you spend a great deal of time researching the facts and giving a complete unbiased view. Very refreshing in today’s environment.
I feel fully briefed on the 737 Max issue now, thank you! (Even though I’m just a passenger! But it’s always good to know the actual facts, rather than uninformed speculations). Your videos are very informative and you seem like a great guy. Wishing you speedy return to flying and a further success with your channel! New subscriber from London.
