I asked Saenz if he'd heard about the line doggie who ran around the back of a helicopter and ran into the rear rotor.

The proposed vehicle features wings on either side of the fuselage and does not use a rear stabilizing rotor.

With a sudden, terrible grinding noise, the rear rotor flew apart.

Ahn-Kha must have been able to see the rear rotor for a second- he fired again.

The rear rotor is damaged, just like he said.

She started firing as fast as she could, aiming for the aircraft's rear rotor.

Then he said he'd lost the rear rotor.

They lost the rear rotor and went in like a stone, straight down from twenty-five hundred.

The helicopter went straight up with only a slight side-to-side yaw as she got the feel for the rear rotor.

But witnesses said the aircraft was above the building when the rear rotor sparked and broke off.
