Professor,

Any opinion/concerns about the thinness of the material?

What factors may affect it and how?

One of the techie articles on the jump mentioned the heat generated at mach1.

My estimate based on a guess of his exit weight and the predicted speed is that some 500kW of heat will be produced. That's a lot of heat.

My colleagues in the aerospace program tell me that most of this will be heating of the atmosphere in his wake, and that the heating of his body will be only a few tens of degrees, easily handled by his suit.
