An initial body resistance of maybe 5000 ohms, voltage between phases of sqrt(3)*44000, you have 15 amps, and a power dissipation of 1 million+ watts. Explosion indeed, I'm surprised they didn't pick his pieces up in a picnic basket.
I saw some workers on one of those "extreme careers" shows. The guys who work on the high tension lines don't even need to touch the lines to be electrocuted. They said that the power would arc from 14 inches and cause immediate death.
