Well,
Concorde's getting quite a bit of focus for these bit's which have a habit of coming lose occasionally;
What's the relative danger? I mean, how often does something like this happen on your average 747? (just for nearest age, obviously there are design differences!!!!)
Can't be all that bad or else BA wouldn't let it fly.
But is no.1's structural probs. per flight figure greater than an average airliner? Significantly so?
Anybody here honestly want to pin a value on years until retirement?!?! (of Concorde
)
