A Cessna 172B pilot in Mexico had to save his plane after his aeroplane propeller detached in flight. Yes, detached. Plonk. You can see the action from the cockpit in this video, including the exhilaration and relief of the passengers at the end.
"I've never felt death so near," says one of the woman who was travelling in the back. "Our propeller fell," repeats the copilot after getting out of the plane, which landed successfully on a road. Skip to the end to see the front of the Cessna without its propeller.
I love how the pilot kept his cool at all times, even thinking about putting the GPS away to avoid hitting the passengers behind with it in case of a rougher emergency landing. And of course, the screams of happiness at the end. [Thanks Iván!]
