The problem was De-Havilland had no experience in building large pressurized aircraft, or large jet aircraft. By the time Boeing built the Dash-80, they had already built several large pressurized aircraft, as well as the B-47 and B-52. In one of the books on the history of QANTAS, there is a discussion about how it was the QANTAS selected the 707. In their evaluation, it became clear that many of the negatives De Havilland had to say about the 707 were a result of De Havilland's not adequately understanding the problems. Boeing didn't need the Comet experience, they already knew from other experience. Also the American were probably better engineers than the British by that time, may well have had access to better design tools even then. A lot of the 707 advantages stem from better engineering analsysis of the problems. Interestingly enough, this same problem also impacted Douglas to a lesser extent in the DC-8 design. They lacked the experience in building large jets. As one Boeing official put it, the 707 always had better high altitude, high speed handling characteristics than the DC-8. We had a lot more experience than Douglas had.
