Wild Well Control has an informative animation demonstrating the process of capping a blown out oil well. [via rc3.org]
On a related note I vaguely remember watching a TV show when I was a little kid (late 70s/early 80s) where they were trying to extinguish an oil well fire using dynamite suspended from a crane. I wonder what show that was? CHiPs or Dallas seem like logical candidates, but I’m really not sure.
