> if you were only referring to the power unit, you would not use the word fighter on its own in the first place.
Sure you would - the sort of power plant you shove into a fighter aircraft, afterburner and all, looks nothing like the big ducted fuel efficient jobs you see hanging off a freight/passenger plane, nor even the diddly things normally seen on a ten-seater corporate jet. Let alone the pulsed engines that people (well, person, well nutter on Youtube) strap onto a push bike.
Put a selection of those engines into a row and ask anyone, they'll go "fighter", "fighter", "lear", "heavy lift". Not "jet fighter jet" or "jet corporate lease, with option to buy, executive conveyance, jet".
Okay, you will have caught them out on the second one, it was a trick question: that came out of a speed record attempt car, which was never armed and therefore was technically was never a fighter (you can tell by the staining from the salt from the dried lake bed race surface).
