Guys, apologies for sticking in my tuppence worth, however, from reading through this thread the collective message that rings out loud and clear is adaptability.
You all acknowledge the limitations and tribulations you are working under, yet have managed to adapt to this to continuously provide the demanded service.

This thread, the ageing transport aircraft thread , the FSTA, JSF and A400 threads provide clear concern from the front end that "things can only get better" .......Hello Dave, Bye Bye Brown.
