It's quite possible that Kenley in the
Bandits Over Kenley mission is in the wrong location. Is it one of the CFS1 default airfields? RAF Kenley was in the same location as the current Kenley Aerodrome which is still used for gliding.

Some important RAF airfields had one or more satellites, most of which which were closed down at the end of WWII. A good example is RAF Tangmere which had satellites at Merston & Westhampnett (now Goodwood Aerodrome). There was also a number of Advanced Landing Grounds (ALGs) built on requisitioned farmland in the south of England for use during the Normandy Invasion in 1944. These were returned to the owners as soon as they were no longer required.
Although bombs were dropped at random for various reasons the Luftwaffe bombing of RAF airfields during the BoB was surprisingly accurate.
