Sorry guys, there will be no tests to confirm the probability of a balsa glider re-entering the earth's atmosphere from space. Due to the pending regulatory actions of the FAA, the glider qualifies as an sUAS and as such is looked upon as a considerably dangerous non-commercial "model airplane". It would violate the maximum 400 foot rule that the FAA is recommending be strictly adhered to by all models and it could potentially violate the pending 100mph limit that the FAA wants to initiate. You guys will just have to modify your "Real-Flight G5" flight simulation parameters to test the theory. But be careful here too as you may be suspected of developing some devious plot to use gliders from space to some no good end, like balsa splinters raining down on an unsuspecting populace below, or some hog rot like that.

Happy Flying!
