(which is an incorrect term as this applies to target aircraft - from one of the very first, the De Havilland Queen Bee)
Not according to the dictionary, B-word:
drone n
1. (Life Sciences & Allied Applications / Zoology) a male bee in a colony of social bees, whose sole function is to mate with the queen
2. Brit a person who lives off the work of others
3. (Engineering / Aeronautics) a pilotless radio-controlled aircraft
[Old English drān; related to Old High German treno drone, Gothic drunjus noise, Greek tenthrēnē wasp]
dronish adj
I suspect that the press has got fed up with the Spams and the Rental Aeromodel Farce inventing new abbreviations and acronyms for pilotless aircraft every few weeks - so they've settled on the simpler term
drone.
