Loadsa fun stuff on 7 odd pages makes me apologise if mentioned before but I recall the BEA Tristars in that l BEA cul-de-sac of Terminal one making a very distinguished, deep, throaty (stop it ) growl into life as , I think, centre engine was started first. Tridents also didn't make the same noise as the 1-11 even when powered by the same Spey,(5-11 was it?). !-11 -300 had same engines as the T1's. Like the tristar, I think we started centre engine first & that might have blocked out the same start noise on the outers. Crikey, I sound like I know what I am talking about !.
