to the bottom of the class! How about Tu154? And the Russians did a little one- Yak40.
Actually I was thinking about the Yak-40, so really messed up.

Completely forgot about the TU-154.
As for the Ford Tri-Motor, whatever the Forker Tri-Motor was called, I
assumed (there's that word again) that they were asking about jet powered airliners.
And I guess the DC-10 and the MD-11 could count as two different aircraft.
(I'll take me beer and go into the corner now.)
