Ricktye:
Watching the video of the ship coming out of the water by hoist, it doesn't appear there like there was little or no power to the main or tail rotors when it hit the drink. Looks like hardly any damage to them, as in they were close to stopped....
Rick, the main rotor blades are indeed undamaged. However in the pictures of the aircraft as it was recovered from the water, the tail rotor blades do look severely damaged.
Rumor now has it that it was the freewheeling unit that came apart, which would make a lot of sense.
