Yes, but maybe not as soon, no doubt work was speeded up when the Comet appeared, even before the 1954 Comet 1 grounding Comet 2 and bigger Comet 3's were under development, Pan Am optioned some of the latter.
Though some airlines, notably the CEO of AA
, at the time doubted that jets would have an impact for many years, clearly the emergence of the Comet got things moving .
Had the Comet 1 not had the problems (which you can bet that other manufacturers took notice of, DH
after all were being extremely pioneering, sometimes you pay for that), the Comet 2 and especially Comet 3, could have sold in the US domestic market, I doubt that Boeing, Douglas, Lockheed, or any major US planemaker would have just stood and watched that happen.
