In 1937 a Japanese Kamikaze plane completed a 51 hour flight from Tokyo to London. In a world where those sorts of journeys usually involved several boring months at sea, 51 hours was crazy, stupid fast. George-Clooney-meets-a-cocktail-waitress kind of fast. George-Michael-in-a-public-toilet fast. You get the idea.
Anyways, the Japanese government was all "ZOMG! Win!" and issued some commemorative postcards to mark the occasion. Four years later they were strapping bombs to the same planes and flying sorties over the Pacific – but that’s another story. One that Ben Affleck and Michael Bay told with understated eloquence in PEARL HARBOUR GOES BOOM!
Point is, the postcards were ace, and the good people at the Boston Museum have recently uploaded their copies. And in case you’re wondering, kamikaze originally meant 'divine/holy wind'. Not the other thing.
