Funny story about the A-400 as a couple years ago when one of the F-15C units was covering the Beach CAP theInteresting there are four A400s in our vicinity this morning - one each from UK, Belgium, and Germany, with a second UK heading southwest about to reach Maine.
route of course overflew Dover AFB area.. There was a Belgium A-400 visiting Dover and the two pilots were checking it out
from above and they had no idea what type it was.. "Strange aircraft looks like a bit like the C-17 but has props!"
This back and forth went on for a while and they never did figure out what it was except it was foreign.
