Also super important to note for others... filing a NOTAM is not getting approval. NOTAMs are handled by LEIDOS Flight Services, not the FAA. They will file the NOTAM however you tell them to, but they assume you know what you're doing and having a NOTAM is not an endorsement. If you're not following the rules, the FAA may still come knocking even if you successfully filed a NOTAM. Small balloons do not require approval of any kind, but it is best to coordinate with the FAA anyways ➡️ olhzn.com/safety
Thanks for clarifying! So, for example what would cause the FAA to "come knocking at your door?" If any of the flight prediction looked off or if there was airline activity in the area that would prevent you from launching?
@@EmilysScienceLab They would "come knocking" if any regular citizen or airline personnel submitted an anonymous safety complaint (justified or not). For example, we had a pretty awesome airplane flyby caught on video ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Cla34QzgbKc.html ) which resulted in anonymous complaints (understandable, but not justified). We were then audited by FAA's FSDO from top to bottom on everything from operations, payload weight, payload density, string tensile strength, parachute size, equipment, etc. Fortunately, we follow all the rules & go beyond so we satisfied everything in the audit, but if they had found something we could face fines or worse. Moral of the story... make sure you cover every bullet point in the regulations (there's not many) and then even go further than that with some common sense safety practices.
So, after all of the recent hoopla about high-altitude objects, and their downing by USAF Sidewinder missiles, I just had to look into who might be involved with high-altitude hi-jinx. I was pleasantly surprised to find your very informative video on this subject. It didn't really take much effort. Maybe our national security officials, and those who report on same, could be equally diligent and answer the burning question of the day.
Congratulations for the new addition to your family! I am a huge space nerd, so your video has inspired me to attempt a HAB flight. I am wondering if there are any additional requirements for a night flight?
For small flights < 4 lbs. technically no extra night flight requirements, but all our night flights have high visibility strobes just to be safe ▶ olhzn.com/16
I enjoyed watching all of your Xploration Outer Space programs. I teach the STEM program in various middle schools. Focusing on basic electronics, learning to solder, and building LED kits. I also had an HF amateur radio station at one of the schools, in Northern CA. Students would come in at lunch time and made contacts. I'm glad to see your new science programs. 73 Darryl KI6MSP
are you sure you can see the curvature? nice you told people about the fisheye lense, but even other lenses distort the image at the edges. There are balloon videos out there without any noticable curvature from 100.000 feet. Your video is really nice, you answered the questions very well. I guess I'll try this one day. But would be very nice to see this video with special non-distorting-cameras so we could be sure if there's a curvature or not.
Thanks for creating this video. I'm just starting on this journey and for fun plan to create a video about each step (I've only started with an intro video). One of my biggest concerns is the distance the project travels and recovering it; some test projections I've used show it traveling very far.
Based on the way the balloon bursts, looks like the balloon failed due to a weak spot (manufacturing defect or pinhole?). A typical burst should explode into many pieces instead of tearing with a single hole.
Aside from the obvious safety concerns, are there other disadvantages or advantages to using Hydrogen? Is one gas more expensive than the other, or easier to find?
Hydrogen is WAY cheaper and does allow your balloon to go higher, but there's the obvious increased safety risk. We recommend any first timers start with helium for safety.
@@MParker8200 It's definitely harder to find a supplier for Hydrogen, but mostly due to purchase volume/frequency, not licensing. No license required to buy Hydrogen... you're on your own for safety. Buyer beware!
Everything Tory said, but I will also add that everyone recommended that I DON'T use hydrogen since this would be my first time flying. Reserved for experts!
I actually had two cameras pointed in opposite directions. One without the ultrasound and one with. So the first part of the video just shows the video from one camera, and then I do a post-editing trick to reveal the ultrasound from the footage from the second camera :)
2 and 1/2 hours from ascension to landing x 1000mph for the supposed spin of earth(that has never been felt nor measured) = 2500ish miles away from launch site. Your payload landed 200ish miles away...sounds about right...pfft
