Let me see it was the one taken shortly after the explosion, before the whole rig was engulfed, with only one fire boat there and just the house burning. the likely explosion source ... hmmmm no picture searching videos -- all I can find is this video immediate stop within first few fire frames, look right at the start, one fire boat ... The fire is quite high, on top of the house, it is like the roof is ablaze.
My question was why was the explosion so high up on the rig. You would expect that would be the last place to catch fire from oil. And furthermore, wouldn't you shield the control room from fire? Unless the control room was deemed to not be in the danger zone if the well blew out on them.
It may also provide a clue why the safety gear didn't work. Taking out the controls and controllers pretty well does that.
A high pressure gas flow coming from a blowout seems very likely.
