I'm wondering if this was a Kestrel or something that is used to scare off the birds at airport. I know several UK airports employ falconers to do this. I'm thinking the hawk got too used to the jets, wasn't scared by them and decided to see if he could get a cheap flight for a vacation somewhere.
@@tedferkin This bird is really recognizable as the peregrine falcon, AKA the fastest animal ever recorded. When in a dive, it can accelerate to speeds above 240mph! It's also very possible that this bird was indeed a falconer's, since this bird is one of the best pigeon predators that exists, and it's been introduced in many cities to help deal with their pigeon problems.
That "incident" at 2:37 took place at Ciudad Real airport in Spain (very close to where I live) and the bird was not a wild eagle, it was a falcon that they used at Ciudad Real airport to scare birds away, which makes it even funnier, when the bird used to prevent birdstrikes approaches departing aircraft.
That F-16 wasn’t practicing landing on aircraft carriers, it was testing the system. Arrester wires at Tulsa and other airports are primarily used for emergency landings for military fighter and training aircraft. It’s to help keep them from over running off the runway during an emergency.
If you’re flying the F-16, you’re not gonna be landing on carriers for the rest of your career. Unless you somehow switch to the Navy later, which, there is no need.
Those arrestor systems are usually retractable, and a NOTAM will be issued when they’re up. He’s not entirely wrong though, some Navy bases will deploy them when doing carrier qualification training, but the ones at Air Force bases are used for emergencies (so can the Navy ones).
This has to be one of your best yet. Your enthusiasm is infectious, and I always learn something. Also, thank you to your parents for the loan of their kitchen!
"your enthusiasm is infectious" Just wanted to echo this as i had the same thought watching; he has such a winning and affable personality. I wish I could even somewhat fake that kind of cheerful, gregarious disposition - but I know it would come off as transparently disingenuous.
For the Dual Engine Failure and stall, I think he had fuel starvation. The engines begins to cut out as the plane begins to wave up and down (especially the right wing) after initiating go-around, by the 3rd oscillation they cutout completely. engine 3 dies first as it got the waved around the most and earliest, engine 2 (center died soon after) engine 1 barely stayed alive, you can see it slowed a bit too. Probably caused the float carb to sink flooding the engine or it just more basic fuel lines and the waving caused the fuel to shift to one side of the tank starving the engines.
That was what I was thinking too. Just never seen it in level flight before. Only seen it, or rather heard it, when aircraft gone inverted during acrobatics.
@@christoffermonikander2200 RC planes are much more finicky with their fuel supply due to the low volumes and thus tight tolerances they operate under.
I'm pretty sure it was what is known as a "throttle cutout" caused by slamming the throttles open too fast. Hard not to in a situation like that, but those of my age or older who learned their engines on simple carburettors devoid of fancy additions like CV diaphragms and even earlier accelerator pumps will be familiar with them. Basically, if you open the throttle too fast, the airflow over the jets in the carburettor rises to near ambient air pressure, and fuel is no longer drawn through those jets. If the throttle is advanced more gently, the engine has time to speed up and increase vacuum through the intake enough to keep that vital Bernoulli effect going under the throttle slides, but if you just yank the slides straight out of the choke of the carb, the airflow is too slow in the increased cross-sectional area to keep the carb functioning. Accelerator pumps were the first (and not very efficient) way of preventing it, where any fast opening of the throttle just injects fuel straight into the intake manifold, but later constant vacuum/velocity systems pretty much solved it - but both add weight and complexity, so may not have been present on the engines on even a large scale model. I know they are not fitted to smaller-scale RC aircraft engines. Generally, the servos can't advance the throttles fast enough for this to happen, but at some point in scaling up models, it could be a problem in tuning the servo response.
@@phillee2814 Yes, sudden full open throttle + marginal carb setup = lean cut. Large engines have accelerator pumps to avoid it, most RC engines don't, you just set them up to run a bit rich.
10:00 my initial thought was with the door open it creates drag along the right side of the aircraft, making the aircraft want to veer to the right, so they can maintain centreline as much as possible upon touchdown.
Hello Joe, I am an R/C pilot and in the clip at 17:13 the aircraft pitched up to hard the fuel ran to the bottom and choked the engine because it wasn't receiving any fuel.
17:34 The botched flare looks like there was a lot of pitch oscillation, maybe negative G for a moment, and significant yaw even before the engine failures. Could these things have caused fuel starvation, by all the remaining fuel flying to the top/side of the tank where the intake isn't? Perhaps engine 1 got lucky by having enough in the lines or riding out the interruption, and the others didn't.
I've experienced the "pitch change causes fuel starvation" issue with an RC aircraft. I had about 3 inches of fuel line between the tank of the aircraft and the engine, and it took at least 10 seconds for the engine to fail after the intake sucked in air. I doubt it was negative G at the fuel tank causing issues. If these engines use float-style carburetors, then maybe it was fuel starvation within the carburetor? The plane I flew had a much smaller engine with a needle carburetor, I don't know if larger RC aircraft use float-style carburetors. I do know that throttling up too fast can cause RC engines to die immediately, though. Maybe that's what happened here? I think the yaw happened after the engine failures, but it's hard to tell for sure.
@@James-oo1yq In a discussion under the original video it said: The R/C Pilot tried a go around and the engines drowned when putting from idle to full power in split seconds.
I know negative G's were an issue in early carburettor fed spitfires because they rely on gravity to supply the fuel, nose down too hard and the engine cuts out.
As for the last clip: Could it happen that G-forces were so big that the fuel pump was exposed to the air in a tank effectively cutting fuel supply to the engines #2 and #3?
@@PeterNGloor I think most rc aircraft use carburetors. It could either be a shift in the fuel which pulled fuel from the fuel lines, a carburetor failure, or he might have pushed the throttles up too fast and killed the engine
That Cheetah incident happened at Air Force Base Makhado in South Africa. That aircraft is a BAe Hawk Mk120 from 85 Combat Flying School. The Cheetah is actually the base Cheetah and has been there for many years. Interestingly enough, 2 Squadron, which is our Gripen squadron, is called the Flying Cheetahs.
BTW, that falcon was saying _catch me if you can..._ Their aerobatics are just fascinating to watch with no plane ever being able to hope to do nearly as good...
On the last video, could the sudden right yaw have caused an issue with fuel feeds cutting two of the three engines out? (Provided those were ICE and not electric motors commonly found in RC aircraft.)
Love this format. I really enjoy hearing your view on things that don't warrant a whole video by themselves. Your insight into things like the Sarajevo approach or the missing wheel landing is so fascinating. It is just this sort of content that keeps me coming back.
Thank you Captain Joe for this interesting series. Especially you can see also funny things happening. Most I was impressed by the Piper flight that lost the wheel. A really super good instructor!
We've got a runway on our farm for our airtractor 802 and my father and brother's planes (Dhc-3, cessna 180, 172, 441 conquest 2). Anytime someone lands a low pass is done first because in the mid 90s my grandfather was flying his 170 and just after he touched down a deer ran out from the treeline. The deer got into the prop and lets just say it was a bad day. Wrote the plane off and peices of deer may still be in the trees. My grandfather was fine atleast.
@@joeg5414 26,000 acres in Saskatchewan, Canada. Both my dad and my grandfather were airforce pilots aswell wich is where the plane obsession comes from. Farm just lets them be buisness expenses so long as we take a buisness trip every year lol. Not an uncommon thing to have spray planes here.
Greetings to Isny, it was a nice little town in the 80s with lot of young people and a great mixture of traditional and progressive minds. I hope it is still cool.
The bird on the windshield was probably a hawk the falconers hired by the airport use to scare away smaller birds. You can see the straps on the bird's legs and a guy on the tarmac trying to call him back. My friend has a Harris hawk, which is awesome. Unfortunately he doesn't work for an airport, which kinda sucks XD
12:54 I've seen this happen from time to time on fully fuelled 747's just after takeoff (perhaps not during takeoff). The float shutoff valves which are supposed to stop this happening don't always seal properly with fuel sloshing around. The fuel comes out of the naca scoops. I've seen overfills during refuelling which is definitely a cause for concern. Not be be confused with vapour trails.

I once had the pleasure to fuel up the real JU-52 when I worked at Mannheim airport and it came for a stopover. Great plane!
4:54 I have a friend who many years ago worked in Angola when it was in civil war. He was flying somewhere and the pilot did that approach. He was in the military plane with a group of nuns and the pilot informed everybody about the approach. However, my friend didn't spoke Portuguese and he didn't realised what was about to happen. Suddenly, the plane goes into a fast nose-dive and all the nuns started to pray loudly around my friend. He was petrified, he literally thought he will die in that moment. When they finally landed, he pucked.
The radio controlled aircraft may have several explainations for crashing....suggestions are Radio control interfearence with rudder servo shift Like the max the engines were too far forward causing a cartwheel stall (demonstrated on the DCs swepped wing design) caused by too narrow C of G envelope. Sudden power loss on one engine flying at low speed.
The bank stall @15:21 as I was watching that I was thinking in my head, "BANK ANGLE!! BANK ANGLE!! BANK ANGLE!!" in the EXACT same voice that the computer uses. XD
Notable mention on that last video as well, a very good moment to explain “ground effect” on an aircraft. It clearly illustrates the phenomena. That with combined with the speed makes it seems as if he just hit an invisible trampoline. 👍🏼👍🏼
The 727 fuel dump out the surge tank was nothing compared with what we went through with fueling a 747SP for a JFK/NRT flight. Crew members couldn't get enough fuel and we always pulled the overflow protection fuse, went down to one truck and one hose and even choked that hose. Still we ended up dumping fuel and the Port Authority was not happy especially if the fuel went down one of the drains. We ended up fitting long hoses to the surge tanks and connected to a 250 gallon fuel bowser to collect the overflow. Especially fun in the summer when the specific weight of a gallon of fuel was light.
He raised the flaps before getting out (PA28 video) because when the flaps are extended the handle makes it really hard for the pilot (left seat) to get out as the piper only has a right door.
The rubber bungee start method by launch squad was standard in the early days of gliding. (And, no, you don't launch an SG 38 into thermals that way. Not unless you start from the top of a high slope.)
In my first unit with the royal engineers I was part of the team that installed the arrester cable at RAF Bronze Norton. Had some very funny moments in those few months work.
Hi Cap Joe!! I love your uploads! Can you please make a video explaining the radio panel on the pedestal like the VHF1 etc. that would be very useful! Thanks again!
19:50 My concern: Engine no. 2 and 3. stopped because of a no fuel situation. As the airplane went up again, he tried to stopp the ascent to prevent a stall. As he pushed the elevator forward nose down, the airplane was in a zero g or even negative g situation. In that moment the carburators of engine 2 and 3 failured.
19:58 RC flyer here. When I was in the military, was in the aerial target team that flew target planes for ground based weapon platforms to practice aerial target shooting on. The planes were ~2m wingspan glassfiber shelled planes with a normal 2 stroke RC engine in the front (nitromethane I believe it used, I'm personally electrics guy). Why did the engines stall on the go-around? Most likely the carburetors got flooded, which kills the engine. The way we used to shutdown the engine during landing was to lower the throttle to zero, let the propeller spool down to the lowest speed which still caused the engine to run (might have been fuel due to vacuum), then you would go full throttle and this would cause the air/fuel-mixture to become so rich that it wouldn't ignite, aka inject too much fuel to the cylinder and this would cause the engine to stall pretty reliably. I think the same happened here, lowered throttle for landing, engines spool down and then with that panic pull-up they applied full throttle and choked number 2 and 3 out.
15:22 location: Airliner Treffen Oppingen // the owner of the model said, that one engine had a flame out - so no thrust - so it turned the plane over. Rudder could not help much.
I don't know if they still have them but the civilian version of the Andover out of Glasgow airport would do a port wing-over and a tactical landing when going into Inverness airport.
Nice to see the gliding part in there I used to be in the air cadets when I was young and got to do the course and was lucky enough to go solo when I was 16, this was with a winch launch and it was out of this world fun, in fact the first time I ever flew was the cadets in a glider, I loved it.
That small plane that lost its left main wheel... truly, a show of GREAT airmanship 👍🏼👍🏼👍🏼 Reminds me of that incident where a solo, learner teenager pilot lost one of her landing wheels. Daaamn, Dad Emotions triggered listening to her conversation with the ATC.
That suction is called the venturi effect it's the wind rushing over the fuel tank opening that causes this because it makes a low pressure environment in the fuel tank
That A330 bank stall , reminded me of that tragic B52 stunt flying accident , Fairchild Air Base, 1994. So sad. Liked very much these series. Happy Landings.
9:51 you're the expert, I'm just making some semi-educated guesses on this...but I would think that having the door open would help in multiple other ways as well. Creates more drag on that side to counter some of the friction from the landing strut on the ground. Also, it would shift more weight to that side....but I just googled that plane and it only has the 1 door, so there's no option for the reverse if it's the right gear missing :-D
The guy on the wing was in Vegas and he was on ecstasy at the time. He had jumped the perimeter fence and got to the end of the runway where this particular aircraft was holding
In some airports they employ Hawks to keep the flocks of pest birds "like pigeons," away, so if a protecter Hawk lands on your plane, its extremely good luck. The birds spirit will watch over your next flight.
The problem with the Junkers is most probably two not optimally setup carbs. If our RC engines are set a little bit on the rich side and remain at idle for an extended period of time (like the final approach on this flight) they can quit if the throttles are opened for a go around.
11:40 it's hard to get out of a PA28 with the flaps down, because you have to walk on the wing after you get out of the door. It's a trip hazard with them down.
