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 ( th-cam.com/video/Cla34QzgbKc/w-d-xo.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.
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
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!
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.
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 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 :)
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.
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.
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
Terrific case study not just because it's a cool project but because you effectively break down the engineering approach to problem-solving.
Thanks James!

Emily, this sounds like fun! You certainly inspired a lot of us to try this. Thanks and look forward for your next video! 👍

Thanks for the video. One question: Why didn't Hydrogen Gas, I'm sure much cheaper than Helium gas?
Because Hydrogen is flammable and much more dangerous to deal with! I didn't want to take any chances!
This was very helpful. Thank you!
What is a radar reflector? And how do we track it cause the methods we are thinking are really rudimentary please help.

What about access? Can any moron off the street buy a crap ton of Hydrogen without any kind of license?

@@OLHZN Thanks for answering this one Tory!
Hey I'm Ian and I love your shows when there on there really cool
Done heaps of em. Awesome
Did you have a timer on your Go Pro? How did you manage to show your ultrasound at the right time?
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 :)
Do you still answer comments here? I'm launching soon and have many questions! :)

Being a ham, did you consider transmitting video via ham frequencies (440/900 mhz ?)

Ooh interesting! Thank you!
Use a lens that has no added curvature to get a better view of earth un-warped -1:52 shows how bad it is at low level!
You should not have used a fisheye camera lens you would have noticed Earth is flat!
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
There is medicine for your condition.
You multiplied 2.5 x1000 😂 that's hilarious
How bout a balloon platform that launches a rocket!
We are going to use normal old smartphones with a lot of insulation
Greetings and Salutations
Oh, space balloon build for exploration how you NEED #hoodoo 😊
Good luck
Thanks
Nice fish eye lens. 😂
Minus the lens distortion and it's flat.
Oh my god. So the earth doesn't actually look like that form the balloon's view pint? It's just the fish eye?! That's devastating news 😢

Thank 4 liking but really are u
