For a long time, Skylon was the only candidate for getting the lift
cost down to where power satellites would make economic sense.

The US splinter of Reaction Engines was so they could test the
precooler at full scale.  Worked fine cooling the exhaust of a J 79
engine on afterburner.  That is about the same as ram air at Mach 5.

Sigh.
