Oh no, it is not like this. I know there were some, or even many, idle days both in the BoB and in the French Campaign. How many times - I can't remember - have I read about operations in May-June 1940 that bad weather made flying impossible: possibly fog, low clouds, airfields (no concrete runways 1940...) soaked with water, making take-off and landing impossible, aircraft which sank in mud… This is true of both campaigns/battles. With the help of meteorological and air force archive in France and in England we could find out on how many days, in both cases, combat aircraft were not able to fly. I guess it would be about even for the season and the weather were approximately the same, with dry, even hot periods too.
