Sorry, grew up in Belfast during Belfast development and can't resist comment. Plan A was a swept wing jet, cut back to a British Fat Albert (with a 'strategic' moniker, but iot would have got there by a week next Tuesday) by civil servants.
Hmm. A swept wing strategic transport jet? Nah, that idea would never have worked, otherwise somebody like the Yanks would have picked it up - wouldn't they?
Aw ****e, they did!
