Here's a video of a major incident in Kansas City in 1959, a gasoline explosion. In it there are quite a few ambulances shown at work, including a Ford van and some Memphians, and wagons. **WARNING** It is graphic, and unfortunately, several firefighters were killed in the explosion which is caught on film, so if you don't want to see it, please don't watch. There is nice video of a modern memorial to the firefighters at the end.
