Comment Slow speed to orbit? (Score 1) 59 59

Is there a reason we do not use a slow speed to orbit?

Say, a large zeppelin floats as high as possible, fires a jet engine to go higher, then a rocket to leave the atmosphere.
Or couldn't a zeppelin carry a Xenon Thruster engine?

Does it have to be short duration, high thrust; never long duration, low thrust to get to orbit?
