For all hipsters in Laos, who don't know the background of the B-52 drink. The name refers to the US B-52 Stratofortress long-range bomber. This bomber was used in the Vietnam War for the release of incendiary bombs, which likely inspired today's flaming variant of the cocktail; another hypothesis centers on B-52 combat losses
("Burns like a B-52 over Hanoi"). (http://en.wikipedia.org/wiki/B-52_(cocktail)) Yes, these bombers were also used in Laos. So please think twice before celebrating with a B-52 drink in Laos.
