Yes I was just seeing if people knew the diff between aircraft fuel and rocket fuel...even the Concord (supersonic transport - SST - Mach 1) used it. most military aircraft That i am aware of again use jet/aircraft fuel.
SS goes into hypersonic speed (Mach 5) upon reentry...


Air Force uses JP-4 and the Navy uses JP-5 due to the need on carriers for a higher flash point. Your sitting on 2 million gallons of it on a CVN.




ya learn something new everyday….

The Saturn V first stage used RP-1, which is essentially JP-1. The Shuttle probably should have done likewise - Hydrogen sucks as a fuel when you have warm surroundings.

The Shuttle is a true glider on landings. The RCS thrusters fire some as it comes in, but that's only to keep the attitude correct - there's no thrust along the line of flight.



I knew of the glider part via the wiki…..but interesting stuff all around!
