Bill Gunston
Jane's Aerospace Dictionary ( Third Edition) I would suggest that his opinion was that of an informed aviation journalist.
All of which which takes us back to the OP.
Haraka out.
Sadly, Bill is no longer with us (I knew him professionaly for a number of years before his passing). I would suggest that maybe the popular vernacular has evolved since Bill wrote that (and will continue to do so), to now include 'drone' as a popular term for UAV.
Edited to add: A quick Google search tells me that Jane's Aerospace Dictionary (Third Edition) was published in 1988!!

Again with the sly barbs. You just can't help yourself, can you?
