"The A400M is an economical, high-speed turboprop aircraft with a cruise speed of Mach 0.68-0.72 and the highest initial cruise altitude in its class, enabling integration into commercial traffic patterns."
In the old DH Comet with a bomb bay, we used to cruise at M 0.69 and could manage M 0.72 without too much penalty. Still not fast enough to integrate with the civvy traffic and usually got us held down to lower than FL280 when crossing the pond !!
Must try harder/faster!!
What's wrong with a fleet of Hercs and C17s????
