Either way (using ambient CH4 or carrying it as fuel) you could do a bit
better using fluorine instead of oxygen as the oxidizer:

The greater reactivity and energy of fluorine should improve the lean
flammability problem.

Ook! Fluorine is much rarer than oxygen, harder to isolate, and, for us
carbon-based bipeds, VERY much nastier. I hope we're not that desperate.

How about a fission-core thermal jet using the atmosphere as the working
fluid? Lower gravity/higher atmospheric density works for us there.
