I very glad the flight was successful and he returned safely. Things like this are good for technology leaps. I wonder if the craft is fully sealed and pressurized or are they in space suits or both for safety.
I take it that it is an unpowered glider on landing.
I am sure they are concerned about the buckling of the fuselage and will have to do some redesign or look for errors in construction.
A project like this could lead to a lighter, stronger Elise!
