Within Douglas this aircraft was known as '909' and for many years was
the only flight test aircraft that DAC owned.  It was originally
intended for delivery to SAS (? not sure), but during flight test an FAA
flight test pilot landed a bit hard.  Main gear touchdown seemed OK,
however when the nose wheel hit one can see a ripple flow backwards then
the empennage breaks off.  <opps>  For some odd  reason the customer
didn't want that particular aircraft anymore, so DAC got a flight test
vehicle.  (The usual procedure to get flight test aircraft was either to
lease one back or, as in the case of the MD-11 program, sell them as
used to FedEx.)
