After limbing and pulling down as much weight as possible, the trunk was felled with the help of a backhoe. There wasn't much left to it on the inside. Rot had hollowed it out to the point that the old thing crushed like an eggshell when it hit the ground.
It's a big file, but here's the video of it when it came down.
