It's the kind of video that puts a lump in your throat.
But it's also a crystal clear demonstration of the training that teaches Naval aviators to keep their cool.
In this incredible clip from the USS Eisenhower, a Navy E-2C Hawkeye surveillance plane coasts into what seems like a textbook landing during a calm day at sea off the coast of Virginia.
As the Hawkeye traps the number four wire, it seems as if the plane made a good arrest. But while the twin turboprop airplane strains to a stop, the cable suddenly snaps, sending sailors on the flight deck scrambling and the plane plunging off the end of the flight deck. It takes a heart-stopping 6 seconds for the plane to pull out of the dive and into view above the line of the flight deck.
