| In May 1928, the USAAC issued a single-seat fighter
specification to which Boeing responded with a
shoulder-wing all-metal monoplane, the Model 96,
which was assigned the official designation XP-9. Low
development priority and production problems delayed
the planned delivery date of the XP-9 from April 1929
until September 1930, the aircraft eventually flying for
the first time on 18 November of that year. Powered by a
Curtiss V-1570-15 liquid-cooled engine rated at 600hp, but actually delivering 583hp, the XP-9 featured a
semi-monocoque fuselage of sheet Dural over metal
formers. Performance proved disappointing, the poor
vision from the rear-positioned cockpit and the
unpleasant handling characteristics resulting in the
test pilot referring to the XP-9 as "a menace". After
initial tests, the original vertical tail surfaces were replaced
by larger P-12 surfaces, but little improvement
resulted and the USAAC did not exercise its option on
five Y1P-9s.

I have never seen this one before until an article in my Flight Journal magazine, February 2012 issue, page 11 showed it and a website to view and download the plans. I have yet to fine the plans but am still looking. If they are available on the internet someplace I would love to see them. After 33 years with Boeing i am still an airplane nut. reply |
