Is it known that the 2 tanks had different temps? I think it was posted here that they are "unheated", but they would have a heat all of their own, or the product would be very thick, I'd guess. Crude is pretty warmed up when being transported through pipelines, IIRC. Somewhere else it said they were under "ambient pressure". I don't know, I still wonder why he put them in different tanks, could be 1) setting off sensors with too much displacement of oil, ie rise in oil level, 2) knowing that after they slowly decompose (?) they will be less likely to clog filters in 2 different tanks. Has anyone heard whether or not he had any kind of line on them to possibly yank them out for reburial when things calmed down. ie tied to the stairs? (no I haven't heard that, just wondering)
