Bit of a thread drift but I had to go to Antwerp sometime in the late 70s with a colleague who was very scared of flying and very noise sensitive.
The trip was scheduled on a BIA Herald direct from LHR, looking out of the window the a/c appeared to be sitting in a large puddle of water but the presence of several fire engines suggested it was more likely to be Jet A 1 , anxiety factor goes up several notches.
BIA then tell us that yes there is a fuel leak and we will be going to Brussels on SABENA . My colleague relived somewhat announced well at least it wont be on a horrible noisy prop aircraft.
And indeed it was not but we were seated just behind the wing on a SABENA 707 with good old fashioned straight through P&W JTs , noise!!!!!
