Helicopter hit by fire truck and disintegrates and explodes.
 

Can't see what type it is, but it looks like maybe a R44? Truck clips tail boom it seems and off it goes. Was it unattended with rotors going? Seems strange to not immediately shut it down at first trouble. Bizarre accident.

This clip seems to indicate some sort of Eurocopter:
