The B727 for airliners, though the 757 is a very close second.

While Douglas might build stout planes, the countryside is littered with Long Beach aluminum. MD-11 stood for More Death and has it lived up to the name, in spades. Only plane to get a Page One article in the Wall St Journal for crashing.
The Galaxy is nice, comfortable, easy to fly, but less reliable than a Lucas refridgerator. Much less! British sports envy our departure reliability. Better reliability and look out world, here we come at M.77. Fecking Ridiculous Economic Disaster, the FRED is.
My two cents, GF
