I have a few questions about Allied plane co-ordination unless someone has any referance material I can look up.I'm aware about the U.S.bombing at day and Britan at night, but am wondering how[if]anyone kept track on if "friendlies" might be in the area. Example;say the USAF were returning from a bomb run w/fighter escort,how would they know if the Brits had a Mosquito raid in progress and not jump them? How would Brit. radar distinquish who was coming across the channel? Where was the first airport established on the French side of the channel? Good reads on this subject?
