Well they already used to fix CO2 scrubbers on Apollo 13, so I am sure
they took a roll on every mission.
True. NASA still files tape like this on every mission. You never know
when it might come in handy.
"the perennial claim that hypersonic airbreathing propulsion would
magically make space launch cheaper is nonsense -- LOX is much cheaper
than advanced airbreathing engines, and so are the tanks to put it in
and the extra thrust to carry it." - Henry Spencer
