"Glided like a set of car keys..."
Good one!
Actually, from looking at the video, it did not seem to glide at all. More like just fell, with a slight forward inertia left over from flying. That thing just dropped!

Bob's the man, he'll help you out...
I'm serious about saving the wreckage...toss it in a bag and hang it on the wall. I have a whole row o' bulging black bags on my shop wall...
