I suppose, the more you fly. The more the chance that you will have to put up with instances of this sort.
I recall a few years ago on an EasyJet flight out of Gatwick. Just before boarding, it came over the tannoy that there would be a delay due to a fault being found with the aircraft.
I actually knew one of the EasyJet staff on control and had the chance to speak to her.
Apparently the captain had heard a noise coming from one of the engines and wanted it investigated before take off.
So of course I asked the obvious question as to how long the flight would be delayed.
She said,
“As soon as we can find another pilot who can’t hear the noise”
