I asked Professor Elihu Rose , an expert in this area of history, and here is the answer:
"Strange question indeed! I don't know the answer for sure but a good bet is that if the aircraft engineers were civilian, they would not have been issued dog tags. But if they were military, they would most definitely have carried "identity disks." So the question is incomplete as posed.
Without knowing whether they were civilian, one cannot suggest source for the answer."
So in other words, British plane engineers in WWII were sometimes civilians and were sometimes in the military. If they were officially in the military, they would have had dog tags.
