IFF 789
Thank-you! I confessed ignorance up front but appreciate the clarification (also from BOAC and a couple of others), and would agree with the lot of you that conclusions drawn prior to FDR recovery are idiotic, even though I ventured one, based on the fact that the 300-series VS floats and so looks to be the obvious culprit even when it ain't.
But I'll stand by my point about the L-188 (Electra). Lockheed turned to everyone (!) which meant NASA, and all their competitors, Boeing, Convair and Douglas, to figure out if something were broke in the design of the thing. With only two makers of big transports left on the planet I wonder of EADS has the same quality or quantity of knowledge pool to draw on than Lockheed had back in the 1960s.
Again, thank-you and I'll shut up now.
