Well, they've tried mail
but it was considered "too expensive". Beer might have been worth it, though.
Anyway, this reminds me of a story I've heard from a former Phantom pilot. A couple of Phantoms, usually stationed somewhere in northern Germany were in Bavaria for some reason or another (maybe it has to do with beer, who knows?). Before heading back north, they decided to bring back some fresh Leberkäs
. Usually, it is hard to get in the north for logistic reasons, but Germany gets pretty small when you have a jet fighter. All was well until they encountered Phantoms form a rival squadron en route and engaged in some friendly dogfighting. That day it was found out that
a) g-forces turn Leberkäs into something rather liquid
b) Phantom Phixers don't like it when you force them to remove Leberkäs-residue form their aircraft.
Beer would probably never so something that cruel to mechanics . . .
