Whoops! Typo! It's 50k! Glad you liked it Matt. We're running HTPB/AP/Al. If I told you the exact ratios, I'd have to kill you :P. The altitude was low for a number of reasons. We had a really erosive burn, and accelerated extremely hard. The 50,000 number assumes drag from the rail buttons (which melted as it went supersonic), surface roughness, and turbulent flow. Without these effects, the altitude could have been as high as 80k.
Ryan, Congrats on the flight. Real nice looking burn on the motor. What propellant formula? Seems like the altitude should have been much more than 5k for an O5000, or was that altitude at burnout?

@ryan101288 Really nice. Maybe a launch tower next time?
