I've always liked the 707, although it's generally accepted that the DC-8 was a better aircraft and has certainly stood the test of time better
the 707, contrary to what some say, didn't kill off the Comet - crashes killed off the Comet! Boeing were well placed to capture an eager market. to quote loosely from a Boeing director at the time, "It's always great to be the first in something, but it usually PAYS to be the second"!
sadly the 707 certainly DID kill off the VC10 - the latter being built to operate from "hot 'n' high" airfield which the 707 couldn't - unfortunately, such airfields simply extended their runways allowing 707s to operate with ease!
great clip Danf - all hail the 707!
