They were built to a specific BOAC spec. And then BOAC changed their minds and went with the Boeing 707. Shame as the VC-10 was a beautiful aircraft to fly in as a passenger; certainly the RAF ones were. The 707 was not! I once spent 22 hours in a 707 and couldn’t walk properly for three days afterwards!
One hundred and four and a half miles an hour. I doubt those goggles and leather helmet would give much protection in an accident. Back in the days when men were men.
