Truth is, I don't keep up much with civil aircraft. Although I have a soft spot for
twin-engine Beechcraft. Just to show you what I mean, my first gut reaction answer
was Douglas. Then I remembered that they went together with McDonnell. So I didn't
want to look totally stupid so I checked up on how McDonnell Douglas was getting along.
Guess what, they don't exist any more. I bet that pissed off the USAF when they found
out their F-15 advisers and spare parts manufacturer closed shop (actually bought out).
Well, I want to guess Curtiss. That ain't gonna wash.
I think I'm just going to have
to think about it for awhile. 
PS: No, I'm not going to cheat. I'm just going to do some more thinking.
