Of course, with the fuselage horizontal pitch at 0, AoI equals
AoA :-)

Exactly right.

Ok, I see now why you said "see the F-8 Crusader".
John emailed me this URL which partially explains it's wing
shenanigans.
http://pacificcoastairmuseum.org/200...Crusader/j.asp

Quote from URL:
"No, the wing isn't about to fall off. It was designed to do
this so that the fast moving Crusader could slow down enough to
land on the carriers. This also kept the nose of the airplane
down during landing so the pilot could see."
Unquote

I still don't see the purpose here unless it's _only_ advantage
is the second sentence in the quote there. Why would an increase
in AOA 'help the a/c slow down for a carrier landing'?...of
course it would 'slow down' BUT it'd now be way high on the
glidepath TOO. Just as it would be if you hauled back on the
stick...the _only_ advantage that I can see for this capability
of the F-8 is to lower the nose for better visibility from the
cockpit. Mind you, that must have been a large advantage imo.
'cause it seems to me that that'd be a big engineering project.

Please guys, tell me where I'm wrong here...

A/c is flying smoothly down a three degree glide-path,
the wing's AoA is 5 degrees. AoI is zero. (guesses of course)

Pilot pops the 'AoI switch', AoI becomes 5 degrees, AoA becomes
10 degrees, a/c tries to climb, pilot prevents that by pushing
stick forward, AoA now returns to 5 degrees and a/c ~returns to
glidepath. (Fuselage is now at a steeper angle than it was).

I'll tell you what will help, explain where I'm wrong in calm
terms or ignore this post. Insults about my lineage, my skin
colour, my mental capacity etc will only make you look bad to the
lurkers and won't affect me one whit. (I'm old and tough
skinned).
