I don't see a thermal-expansion tank in pic, maybe that's why there is a cap on T&P relief line. Very dangerous situation.

Yeah, but it took them like 5 or 10 tries to get it to go like that.

They had to keep playing with the amount of water, and the temp.

Along with water heater sizes but it's well established that they can and do blow off like that on a regular basis without trying to engineer a bigger boom like Mythbusters likes to do.

When I was a kid, working with my father, he did a ton of residential boiler work. Boilers were never too popular around here, but there was a builder, that built about 2 to 2.5 square miles of homes, with radiant heat, hot water boilers, & my dad was well known to be the guy to call. I never seen a water heater with plugged T&P valve, but I seen plenty of boiler T&P"s capped, & thought nothing of it back then.

I can remember my Dad scolding the customers back then, & telling them that that is now no longer considered a boiler, but a potential bomb. I thought he was exagerating a bit, but not now. Now I know why he was so adament about it. He said he seen 1 blow through the roof.

1st time I seen something close to this was when a customer disconnected, what we called, a side arm heater. This heater was a little tank inside the boiler, that heated the domestic water. When we would disconnect them, my dad always left the ends uncapped, & cut off the threads. Don't know why or if he could of taken them out but he didn't. Well this customer disconnected their own sidearm heater, then they capped the inlet, & outlet. Took only 2 days for it to rupture, & blow out sides of boiler. I can't imagine haw bad it would be if the whole boiler exploded.

About 10 years ago, a homeowner in Decater,Arkansas plugged his T&P valve before going to work the night shift in the local poultry plant. At around 3 am he got a call to come home. The tank had exploded and shot thru the ceiling and landed in the field behind the house. The home was roughly 800 - 900 sq. feet. The explosion had enough force that it turned the home 6 inchs on the foundation. The man lived alone and luckily no one was injured.
