Take-off crash 'n' burn didn't kill the Concorde, it was just too bloody expensive to maintain

Heating not pressure

"This was an aircraft that flew so high, at 60,000 feet, you could see the curvature of the Earth, and so fast that the airframe stretched, gaining between 15.24 and 25.4cm (6-10 inches) during flight thanks to the extreme pressures."

Given the difference between sea level and space is only 14psi, it was the aerodynamic heating that made the thing expand, not the pressure. See also SR71, which leaks fluids until it heats up.
