	Yes, the crashed, but not like you imply.  The #1 aircraft was
doing a certification landing (flapless?) with a FAA pilot at the
controls and he landed hard, resulting in the tail cone breaking off.

	The #2 aircraft was damaged doing a certification landing with no
hydraulics.  The pilot lost control, went off the runway and collapsed
the gear.  Trying to pick up the aircraft with two cranes, to blow the
gear down, one crane tipped over and guillitoned the fuselage, down to
the window line.  Swissair was supposed to take delivery of the aircraft,
but refused it, due to the damages.

	Hardly big time crashes....
