i dont think Concorde's runway length is 10,000+ feet
i dont have plain evedence of this but i do know that Concorde ust to be used for flights out of leeds bradford (7,382) and Newcastle Airport (7,641 ft) whisle fully loaded, please change the runway requirments
when i went onto the used aircraft page i went to lease a concord and it said this aircraft isnt available anymore or somthing like that, so i went back and leased another, now ive got both the aircraft (concords) and its left me in a bit of a financial situation
