ATC Watcher: Not entirely true.
Your dates are a little confused;
B747: rollout 30 Sep1968, first flight 9 Feb 1969
Concorde: rollout 11 Dec 67, first flight 2 Mar 1969.
So the first Concorde flew after the rollout of the B747.
Concorde's fly by wire was all analogue, so bears little relation to the later Airbus digital FBW.
