So you think that Concorde was a completely developed aircraft at time of first flight (which the A380 was)? Delays in A380 were mostly due to production issues for cabin, so the aircraft itself was Ok for service from December 2006. The problems were – from a pure aeronautical engineering standpoint – indepenedent of the aircraft itself. Even a B320 can have delaying production issues.

Nope, I did not say that, nor did I think it. I’m not ignorant.
