Can't find the video. However, I have been in the boiler room on a few occasions when a boiler blew up. Let me change the wording as was explained to me by a Pa State Boiler inspector. When there is an explosion caused by the fuel in the boiler that is called a "furnace" explosion and when the pressure vessel explodes that is a "boiler" explosion. All my events were "furnace" explosions and all were eye openers. The first explosion was with an Erie City water tube high pressure steam boiler that was cold and needed to be started. With out my knowledge, the gas/oil selector switch was replaced by the head electrician. I arrived at the site, did a visual check of the boiler and turned on the on/off switch to fire gas. The mis-wired switch put 120 volts directly to the 2 gas valves when the on/off switch was actuated, and after the burner purged and the pilot lit, there was a big bang, and that was the event. All the windows were blown out of the boiler room onto the street, the front burner mounting plate was buckled, and a lot of the internal fire brickwork was shifted a lot. This happened on Friday the 13th I believe in 1974 or 1975. Of course the company I worked for was charged with the mishap and their insurance paid the bill. I had trouble hearing for days and I still blame that event on my hearing deficiency. There were a few others but this was my worst.

Oh I rather agree. Redundancy is good. And, in fact, most ships do have pretty good redundancy -- provided there is time. Evenalmost all the accessory equipment for the main engine is duplicated. There is, however, only one main engine. Very few cargo ships have more than one main engine. Many cruise liners have two or more main generators, which in turn power electric motors which move the ship and provide other power on board, although even there certain electrical faults can black out the ship (there was a big ferry a few years back in British Columbia to which that happened).

It will be interesting to see how much control they got back over their rudder. A look at the track chart suggests that they may have gotten some back -- but I assure you, having done it, that on any reasonably large single screw ship or boat at minimum steerage way, if you don't have the prop wash over your rudder you are pretty much a passenger for any significant and quick course change.

They simply didn't have time. I'll grant that the engine shouldn't have quit. But... engines do.

I will maintain that the lack of fendering on those piers, particularly with the example of the Sunshine Skyway, set them up in the accident waiting to happen class of emergency preparedness...
