It was a very different shape.\n\nSome highspeed vehicles did experience severe heating, notably the \namazing X-15 craft.\n\nThe question is a good one, but the answer has needs to consider far \nmore than frictional heating, since that accounts for only a small part \nof the energy that is converted to heat during re-entry.\n\nI have no idea what the equivalent ratio is on the way up, but it is a \ndelightful puzzle.
