Couple of times there, he was lucky there was no tractor coming up the road than forcing him to deploy his ample grass-field skills.

That is perhaps the best summary explanation of Chernobyl physics. The one thing he didn't touch on was the chemical contribution of the graphite moderator. After the steam explosion the graphite fire contributed to the dispersal of the fission products. I seriously doubt the core went prompt critical though when this happens it's so fast that normal time perception isn't sufficient to understand it. That's why reactor controls and startup protocols are designed to raise power levels on the order of many hours, even days. On another note, I am continually amazed at how smart our early engineers were when they designed our initial reactors. The BWR, for example, inserts it's control rods from the bottom. Now you know why.
