War works up a thirst!

13 June 1944: An English brewery donates a sizable amount of fresh beer

 

For the troops fighting in Normandy and a unique delivery method is created,

 

Strapping kegs to the underwings of Spitfires being shipped to forward airfields.

 

Flying at 12 000 feet chills the brew to perfection

 

Presumeably the amount of head when served depends on how rough the strip is?
