Snip...

The questions remain. Why? How? No one seems to have any answers but we
haven't visited the location to ask. Too scared to find out? ;-)

I had a flashback upon initial glance...a BAC-111! Haven't seen one of those
since about high school days in the 1960s.

Just to make this thread "soaring legal" (undetectably dry humor there?), I
believe it was the BAC-111 design that led to the awareness - and ultimately,
acceptable understanding - of the "deep stall" with a T-tail effect. The
prototype of the BAC-111 was destroyed during flight test in a crash
attributed to deep stall. Later, NASA (including one Einar Enevoldsen of
today's Perlan effort) did their own deep stall investigative series using a
modified Schweizer 1-36/"Sprite" (article available in online "Soaring" mag
archive). I've read (somewhere) that Hawker-Siddeley (formerly Hawker, later
formerly many others, later later British Aerospace) gave their BAC-111-based
deep stall investigative data to (then) Douglas, which enabled Douglas to
considerably shorten the development time of the DC-9. If true, yet another
instance of cross-fertilization within the international aerodynamic community...
