I don't know. Gliders are a thing, dragged into the air by a propeller driven plane, untethered they fly for quite some time. https://en.wikipedia.org/wiki/Glider_(sailplane) https://en.wikipedia.org/wiki/Glider_(sailplane) I estimate, speculatively that the energy to bring it to altitude, condensed into an impulse only imparted at launch, would destroy such an aircraft and kill any occupants.
