Biggus,
You are not alone in having lost friends and colleagues in the RAF.
Wailing and moaning here does nothing to improve anything. Some people seem to enjoy that sort of thing as though they are doing some good. They are not.
Airbus have a very good reputation for investigating incidents and circulating the results and advice. They have a vested interest in establishing and maintaining safe aircraft that operate to specification. But it doesn't happen quickly unless it has to.
