Comments;

1) Rare video of a rare event. I wish that the videographer had kept
videotaping.
2) The NTSB report says that the wing separated "at the
wing-to-fuselage attachment point." Wrong, it was clearly outboard of
that. Seems like an odd place for a multi part wing to be coupled.
3) The NTSB report says that the "glider descended back onto the
runway". I don't see it ever lifting off.
4) If the plane never left the ground, why was the FAA and NTSB
contacted? Insurance purposes?
5) What is the tow plane?
