I really liked how he mentioned the cryogenic strength of 301 Steel, and I’m in love with KISS simplicity of it all. Transpiration specifically is out, but unmentioned is a real need to manage thermals of the craft, not just on re-entry, but on a journey to the moon. I refuse to count out some kind of neat thermal fluid tech helping out with this, mostly cause I admire the raptor engine nozzle tech! Even bad ideas can yield a bit of good. STS needed to open doors or get back down cause she would have cooked. The ISS has 2 triple sets of huge radiators!
