Which, then brings me to another question: Why did the RAF have so much difficulty coordinating fighter escort? They could never seem to get their fighters and bombers in the same basic area of sky...
1939 - May/June 1940:
-RAF: what do you mean 'fighter escort'??
-French AF: there is no such thing as 'fighter escort'.
-USAAC: fighter what?
-Soviet AF: fighter escort? Do you want to spend some time in Siberia?
