there definitely was a compressibility problem, mach tuck; the

stage. The engine rotation switch was early on in the program
according to Ethell; I believe in the YP38 stage before the first
production run. If I'm not mistaken, the high mach dives came
after
the switch but I'm not at all certain of that.

All the -38s sold to England had same rotation direction engines
on
both sides all the way through. Just another odd thing...

Are you sure about that?

Bertie
I heard the same thing. The Brits raised hell about what they
considered
a high degree of possibility for unnecessary maintainence due to the
handed engines. On the practical side, the Brits had ordered a ton
of
P40's which used the V1710 Allison with a right handed prop. The
word
we
got was that the brits wanted the Allison's on the 38's to be
interchangeable with the P40 to cut down on cost.

Found some info on that in an old book I have. Apparently there were
a
handful of unblown 38s delivered to the RAF with both engines RH but
they had a lot of problems and the remainder all had contra rotating
engines.


Bertie
That's right on the Turbo Chargers. The Brits believed they wouldn't
be
fighting at the altitudes where the Turbos were an advantage.



According to the ariticle on the website they were inherited from a
French order and the French wanted them without to avoid delays in
deliveries. Bertie
That one's new to me, but highly likely :-))

There's a lot of strange airplanes out there. We once had a vendor come in
and try to sell us an aluminum thickness test tool. We went out on the
finished line at Renton and randomly went up to one 737 and did a quick
check of the right and left wings. His tool showed the sheet metal was a
few mills thicker on one side. We challenged it and sure enough he was
right. During final flight checks the plane had to be rigged uniquely and
cost a seat or two. Every airplane has a set of manuals assigned to it and
they had to updated too. The airplane sale went through at a discount to
the carrier. So look for a lopsided 737 out there. Now you know the rest
of the story.
