I actually experienced something that looked like this, without the mushroom cloud and radiation, and with a much smaller shockwave. January 25, 1969, Southern Railway train #154 derailed resulting in the explosion of several LPG (liquid propane gas) tank cars just 3/4 of a mile from my house. I had just gotten in bed after our Friday night gig as house band at a club in Biloxi. I reached up to turn off the lamp on my bookcase bed and before I could, it went out. I heard a rumble that sounded like thunder, and the curtains in my bedroom turned bright orange. My parents and I got up to see what was going on and when we looked outside, the whole world was orange. A friend of the family owned a moving business very close to the explosions and we drove to see if we could figure out what was going on. We were turning around in the parking lot of a convience store just two blocks away when one went off. It got very warm in the car, even though the engine had not run long enough for the heater to work. We left the area rather quickly. The story made the national news and when we returned to the club Saturday night, we were greeted with shock and statements of "we thought you got blown off the map." They did not know how close to the truth that was for the few blocks surrounding the derailment. But, it could have been worse, if not for the quick and heroic action of a railroad employee who managed to detach a number of cars that had not left the track and move them far enough away that they did not explode. We were lucky that there were only 2 fatalities, 33 injuries, destruction of 54 homes and damage to 1,350 buildings.
Trust me when I say, you do not want to witness a railroad tank car fly two blocks in the air from a close vantage point.

Exactly. Except it only flew about two blocks and landed on a house. Somehow, the occupants survived.

Yeah, I've seen that one before. You'd think firemen would know better.
