Concorde Question
 

With the Concorde's high pitch attitude on arrival, and departure
anyone know how common it was for the tailwheel to make contact, curious.

I only have one small piece of info that I can give you:

A tailwheel ground contact will occur at 12.5 degrees if the wings are level.

Bellerophon and Twotun should be able to help you out with the rest.

Regards

Edit: I dont think that the tailwheel contacted the ground very often, otherwise we would have seen more incidents in which the engine nozzels were damaged.
