Aero Class Final Project Crash

This was our final project for Aero. We tested our plane extensively indoors and it flew well, but the thermal drafts of this arena caused ours (and almost everyone else's) to go up and to the right, eventually stall, and then crash into the railing. Almost everyone crashed at exactly that same spot.
Needless to say, after 40+ hours of build time we were very disappointed in what occurred.
