My friend George Fulton sent this to me. This excerpt addresses settling with power and how the pilot did the best thing in a bad situation.

Extremely well-written behind the scenes article detailing the raid on Osama Bin Laden, from the New Yorker. Incredible:

Excerpt detailing the helicopter crash:
“When the helicopter began getting away from the pilot, he pulled back on the cyclic, which controls the pitch of the rotor blades, only to find the aircraft unresponsive. The high walls of the compound and the warm temperatures had caused the Black Hawk to descend inside its own rotor wash—a hazardous aerodynamic situation known as “settling with power.” In North Carolina, this potential problem had not become apparent, because the chain-link fencing used in rehearsals had allowed air to flow freely. A former helicopter pilot with extensive special-operations experience said of the pilot’s situation, “It’s pretty spooky—I’ve been in it myself. The only way to get out of it is to push the cyclic forward and fly out of this vertical silo you’re dropping through. That solution requires altitude. If you’re settling with power at two thousand feet, you’ve got plenty of time to recover. If you’re settling with power at fifty feet, you’re going to hit the ground.”
The pilot scrapped the plan to fast-rope and focussed on getting the aircraft down. He aimed for an animal pen in the western section of the compound. The SEALs on board braced themselves as the tail rotor swung around, scraping the security wall. The pilot jammed the nose forward to drive it into the dirt and prevent his aircraft from rolling onto its side. Cows, chickens, and rabbits scurried.”
