Patronising?
Poor grandad much have been SO scared, I am amazed he made it through the flight. All that nasty noise and tight turns.
Guys of his generation grew up during the war and would be the first to sacrifice their lives for King and country. Remember all those young pilots that flew off to defend the UK in the air with far fewer hours that we need to gain our PPL.
Grandad should have clipped Information Delta round the ear!
