As the title says. Would we have the TSR2, CVA 01, hundeds of Concordes, Advanced Passenger Train, Nimrod AEW3 and others that I don't know about if British project managers were the best in the world. All of these projects were cutting edge and difficult but all got close to fruition and were held back by abysmal project management after the expenditure of huge resources. Are technology issues inherently solve-able in an environment were management is excellent?
