This couple had their adventure end before it even started. Both were very lucky to get out alive.
There it is… blame the mechanic right away….Probably blew a fuel line. If you notice when the guy hits it with the extinguisher, it lights up from the ground. And not from the bottem of the van. So my guess is a fuel line. I would be interested to know what the mechanics did to it. Not that it matters, stuff can break as soon as you leave a shop. Glad they and the FFs weren't hurt. They parked thier rig almost under to the overhead wires. At least from the angle I saw. The van was directly under the primary wires. It dosen't happen often, but the wires can heat up and break. Then they fall. An electrified peice of fire apparatus is not fun. Cars and vans go up like that all the time. Plastics and foams. Its like solid gasoline. The propane may have went off later, but was just pushing out the top. So, no explosion, thats really just in the movies. A tire may let go or a air shock, but thats mostly just noise. The propane tanks can go boom, but if it was open probably just feed the fire at a normal rate inside the van. But its a concern. Anyway, thats my take from the video.
