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. The troops love it, but the British Ministry of Revenue and Excise steps in and informs the brewer that it is in violation of law to export beer without paying taxes on it. End of “authorized” beer runs. June 13, 1944.
