Can you send another unit?

This didn't happen to me but to one of the other crews at work. The crew had just found the address and was doing a three point turn so that they would be facing the right direction to get to the hospital. As they were in the middle of the turn (blocking the street) the drive shaft to the ambulance came off and started to roll away. A rather distressed EMT called into the office asking if we could send another unit. This story just makes me laugh.
