"No get out" clauses ...
The clause to "keep the French in" the Concorde programme seems to have been carried over to the Typhoon and caused no little squirming in the White Halls, as the biter got bit once again ...*
Re: Roly Beamont's comments on there being no need for MRCA/Tornado if TSR2 had not been stopped rather beg the question - with Tornado, the RAF (eventually) got a "near TSR2" more cheaply as the cost was shared with Germany and Italy. Dropping the internal war-load carriage shortens the fuselage (but needs a bigger fin due to the shorter moment arm), while swing-wings avoid the complications of blown flaps and perhaps make the aircraft more "handy" at low speeds than the TSR2 is said (thanks, BEagle for that info!) to have been. TSR2 can thus be seen as a pregenitor of Tornado, so something at least was saved from the wreckage ...
*PS. I do realise that France wasn't in the Tornado programme, but the principle applies ...
