We cannot let this thread be consined to the annuls of forgotten history
There must still be a million questions that you always wanted to ask about this wonderfull plane
So here is mine
On Wikipedia they tell us there were 20 Concordes built, 14 production and 6 pre production
Also Wiki tell us there were 67 olympus 593 engines built
Forgive me but this does not seem possible, not enough engines were built to satisfy 'new' engines for 'new' planes on the production line
Does this mean that the 6 pre production a/c donateded some engines to production aircraft so some BA and AF planes flew, even from new, with 'used' engines??
Many thanks
