I was browsing around and found some intresting articles about there is some debate whether or not a metal cover for a underground nuke test a few months before Sputnik made it to space or not. Pictures from the test (launch??) give a lower bound of its velocity at 56km/s. the main argument agianst is that it would have blead off the speed in the atmosphere. anyways, kinda cool

What is the stagnation temperature in front of a generic manhole cover moving at 60 kms-1 through a standard atmosphere? The answer doesn't seem to be in the literature. Do we have a good aerodynamicist among the members? A ballpark guess would be well over 10,000 K.
