Practicing flight formation...
Very short caption with this photo.Did this really happen like this?I wonder if you can learn formation flight this way.

You got to be joking?

Night before D-Day. This is the fuselage of a Horsa glider; some paras decided to write some messages for Hitler & Co. Notice some words have been erased.

IWM caption: "Once the Blitzkrieg had begun, the Hurricane squadrons in France were plunged into almost constant action, flying interception patrols and providing escort for RAF light bombers. Their airfields were subject to frequent Luftwaffe strafing attacks, with little or no warning. Here, personnel of No 85 Squadron at Lille-Seclin check air activity overhead while in the background two Hurricanes sit at 'stand-by', their pilots strapped in ready for immediate take-off, 10-12 May 1940."
