Dad once told me they got chilled beer in the Pacific by filling the ammo bays in a P-47 with beer bottles and flying up to 30,000 feet or so where it was 20 below zero.

Then there was the "beer run" from the supply base - they'd strap cases of beer in the bomb bay of a B-25 rigged to the bomb shackles, so they could drop the extra weight if they had to run from a stray Jap fighter. And reeeaaallly, reeeeeeeeaally hope they didn't have to.
