that the 700 was a
pretty badly designed heap of crap - Winton being the prime
example.
So was the Lockheed Electra where several were lost because of significant inflight structural failures to the outboard engine support structures and the inboard portion of the port wing. These were the components which appeared to have been involved in the catastrophic disintegration of the aircraft.
And of course the Comet 1 structural failures in flight and not to mention the Canadair C-4 Argonaut with its poorly designed fuel system - Stockton, Manchester accident 1967. The list goes on.
