I suggest there was more than one sleepy pilot.
The guy who used to terrify me had the same initials as a Swiss numberplate.
VC10 captain retired, they were so concerned about the load he was carrying, they removed his thin stripe to help him with his burden.
In the climb, he used to scream 'I hate this ****ing aeroplane' and hammer the glareshield with his fists.
I used to have to nudge him awake to change the Squawk . . .
Happy days . . .
