The cocpit temperature of the Blackbird was over 400 degrees. The space suited pilot could bake a cake in his lap. That was Mach 3.4 and the titanium was at it’s thermal limits. Good luck.
Gonna need a bigger air conditioner.......................
The jet glowed from the heat but the cockpit was pressurized and air conditioned and the pilot and WSO wore space-suite in case of decompression. . .wouldn't do to lose pressure and be sitting there in nothing but your green nomex flight suite.
Flying above 50,00 feet today requires you wear the space-suite. . .regulations. . .not saying I EVER went above 50K, not saying that, but it is a spectacular view from up there. . .
