JohnAx,
Not a real useful post. Just a "?"?? There are some rumors out there I'm sure. Were you just curious in general? A search of the internet might yield more results.
However, you can learn lots of great things through the combined knowledge of everyone here. To do that it would help to have some context for your request for information.
As for me, I'm curious about the Concorde because next year I would like to redeem frequent flyer miles for a trip. This is my one chance to go Mach 2 and I'd like to do it before metal fatigue sets in

.
I hope the planes are soon back online, and better yet that BA offers a "mileage sale" to encourage folks back on.
