I wasn't impressed at the over emphasis on what was going on on the ground. Which squadrons were engaged? What aircraft were used? RNAS involvement? What were the loss rates? Total losses -men and machines? These are the matters that could and should have been addressed in a programme that claimed to explain where the RAF were at Dunkirk using newly released information. There was nothing I didn't know already from our lessons on RAF history at Halton back in the sixties.
