- On April 6th, 2024. Walter Lohmueller and Elijah Sohn(with lots of help) broke the world record for highest recovered flight by a high school group with his rocket dubbed "David"
I've been working on this project for almost a year, starting in June of 2023. After several subscale test flights and motor firings I flew this project on April 6th of 2024, breaking the world record for highest recovered flight by a High School group in the process.

Thank you all for supporting me as I worked towards this crazy project.
So cool, congratulations Walter! Excited to see more!
That you were able to get it in a relatively SOLID state is amazing
The fact that you were able to RECOVER it after w weeks speaks volumes
Dude so cool!
Congratulations, that is an outstanding effort. :)
Amazing job Walter (and team)! So bummed I missed the launch :(
This is incredible, and a very inspiring. As another high schooler working on the same thing, how were you able to get permission from FAR to launch even though you are under 18?
FAR is great because they don't care how old you are and have effectively no rules about who can do EX motors.
Could you please share your 'takeouts' in pdf format...if you can.
Awesome!!
Amazing job man
He be cruisin'
Wow.
Great stuff! I wonder if you have to let the government agency know about this before you launch it or the area you're in is a free airspace.
This launch was super cool to watch IRL, congrats! Spaceshot next? 😁
Thanks man!🤫
can you please launch on a less windy day next time that hike was not very fun 10/10 you are crazy dude
When you go Mach 3 at such "low" altitude, and your fins are full carbon, do they not start to burn/melt? I am designing Mach 3-4 rocket fins and the temperatures were way to high according to CFD to have an exposed carbon leading edge. I'm guessing it only went Mach 3 for a small amount on time, but did you see any melting or burning at the leading edges?
There was no sign of heat damage on the leading edges of the fin can. We used a epoxy coating on the leading edges of the fins to help prevent heat damage to the carbon fiber.
i recently made water bottle rockets that use compressed water as thrust for the rocket, but that is nowhere as close to your amazing rocket!!!
73 g's is crazy! Are multistage rockets no longer a thing?
You didn't hear it from me, but you might want to stick around...
Is it dangerous for the passing planes?
Yes for sure, maybe he has a permit
I launched at the Friends of Amateur Rocketry Test Site which has a standing wavier of 250,000 feet.
