Having flown on a number of 'Dimsod' sorties over the years, I know exactly what the crew were really trying to sniff out. Curry.
This part of Yorkshire is famous for its curries. RAF 'Dimsod' aircrew like curries, that is why they are all fat.
You will find E3D and VC10 crews are much the same, so keep on spotting if you live in Yorkshire.
.........chapati anyone?
