Well, it might be safe to tell you all almost 20 years after the fact, that I was responsible for an army landrover burning itself into oblivion back in 1987. You see, I was an uppity young sergeant back then, and when washing the vehicle with a high pressure fire-hose after a long and muddy exercise, my corporal suggested to me that I shouldn't use the hose to clean out the interior. "No worries mate" I said, so off he went, basking in his own importance.
As soon as he got out of sight, I opened the doors and hit everything inside with a few hundred gallons of H2o, then parked it in the sun, and a couple of hours later, it looked like it'd just rolled off the production line. Anyway, my little corporal was returning the vehicle to the loan pool the following day when it mysteriously caught fire under the dash, spreading quickly to the interior of the cab, all while he was driving down the highway at 60 Mph!
He didn't have time even to get the fire extingusher out of it's place between the seats, all he could do was pull off the side of the road, jump out, move off a safe distance and watch as the gas tank (under the drivers seat) erupted into a ball of flame, and by the time the fire truck and cops arrived, it wasn't much more than a pool of molten aluminum. There was a short investigation and I was questioned, being the second last driver, but I held my nerve and just expounded my knowledge of "dodgy" British electrics, and that was enough for the investigating officer, "case closed", ha ha! Cheers, "Guilty your Honour" Terry.
