ETO - France: Day 8 of 49 of Operation OVERLORD, the Allied invasion of Normandy, France, known forever simply as D-Day. D-Day+7: 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.
A "Beer Truck" Spitfire
Flying at 12,000 feet would chill the brew to perfection. The troops loved it, but the British Ministry of Revenue and Excise stepped in and informed the brewer that it is in violation of law to export beer without paying taxes on it. End of "authorized" beer runs.
Nazis in France had been known to foul the local drinking water, so the beer was more than just a refreshing reminder of home.
Another unique delivery method used auxiliary fuel tanks (normally dropped during long range combat missions) which were steamed out and filled with the brew, which held a lot more than the strapped on kegs.
Although the beer runs were terminated for tax reasons, various enterprising squadrons found unofficial ways to refurbish their stocks.
