The Daily Telegraph reported today that next month, 50 of British Airways most frequent customers have been invited to join the chief pilot of the Concorde fleet in an inch by inch examination of the of the first of BA’s seven Concordes to have completed safety modifications to fuel tanks and landing gear as well as a 14 million pound cabin refit. When the 50 top executives come to Heathrow next month, it will be to look all over the aircraft, touch it, feel it, squeeze it and see exactly all the work that has been done. In April, BA will be putting on a similar presentation for their top 50 customers in New York.

The first technical proving flight and then the first route proving flight and then finally the first flight are expected in late spring or early summer, however a definite date is unknown because they “simply don’t know.” It will take a collective final approval to relaunch the plane into scheduled service, according to BA.
