***CAUTION/DISCLAIMER: Launching things into the stratosphere can be DANGEROUS! Please contact the FAA before trying any launches (even if they are under 4 lbs.) to make sure your vehicle won’t be entering restricted airspace and PLEASE check the University of Wyoming’sBalloon Trajectory Predictor(or a similar website) to make sure you balloon won’t be landing in the city/a populated area where it might cause significant damage. Also, be sure to test your balloon’s terminal velocity for descent before launching. We tested our parachute/payload for safety, made numerous flight path checks to make sure we were not going to endanger anyone, and adhered to FAA regulations. Additionally, we went to the local FAA office to talk to them about unmanned balloon launches and recommend anyone trying this do the same.
