I second Billy 'Moon' Walker.....that takes sky to the next level.
Also think: Moonraker, the Ian Flemming James Bond novel:
"Essentially, the Moonraker rocket is an upgraded V-2 rocket using liquid hydrogen and fluorine as propellants. It can withstand the ultra-high combustion temperatures in its engine thanks to the use of columbite, which Drax has a monopoly. Therefore, because the rocket's engine can withstand higher heat, the Moonraker can use more powerful fuels, greatly expanding its effective range." (Wikipedia)
