Meteor v Vampire.
Charliejuliet,
Thanks for the information. As far as as I was concerned, the Vampire's plus point was its endurance (almost the double that of the Meteor). IIRC, all the Auxiliary squadrons were equipped with the Vampire, as being easier to fly and only half the number of engines for the part-timers to maintain.
Each (Aux) squadron would have one T7 for I.R. practice and rating checks.
I am sure you are right about the very heavy T7 (18,800 lb). Must be the one with tips and ventral full (total 505 gallons). I only flew one once in that condition, and frankly didn't notice much difference.
Cheers, Danny.
