I recall flying from Dhahran to Bahrain on a VC10 on several occasions.
I did that one once - as pax - on a VC10, can't remember if it was Gulf or BA (might even have been BOAC
).
Hostie doing the announcement had a fit of the giggles as she announced something like:
"Flight time of 12 1/2 minutes at an altitude of 7000 ft!"
I might have the figures wrong - it was 40 years ago - but you get the gist .....
