tongue. During the Vietnam War, scientists made a study to find out when naval aviators were under their greatest stress during a mission. Their cardiac monitors told the scientists that getting shot at in a bomb run was not even close to the stress of a night carrier landing in heavy weather. In order to make carrier landings easier and less fearsome, the Navy has developed a series of automatic and assisted landing aides to help pilots get their aircraft onto the heaving, pitching deck. But once you’re there, how do you stop thirty or forty tons of aircraft that have just slammed down at something over a hundred knots?
Well, you attach a hook to the tail of your aircraft (the famous “tailhook”) and “trap” it on one of a series of cables set across the deck. These cables are woven from high-tensile steel wire, which are stretched across the after portion of the ship. Usually four of these cables are laid out along the deck. The first is placed at the very rear of the carrier (called the “ramp” by naval aviators); the second a few hundred feet forward of that; and so on. The last goes just behind the angle that leads off the port (left) side of the ship. This creates a box into which the pilot must fly the aircraft and plant his tailhook onto the deck.

What happens if a pilot misses the wires? Well, that is another issue entirely. CTOL carrier landing decks are angled to port (left), about 14° off the centerline. This is so that if an aircraft fails to “trap” a wire, then it is not headed forward into a mass of parked aircraft. Instead, the aircraft is now headed forward to port. This is the reason why on every landing, as soon as they feel their wheels hit the deck, pilots slam the engine throttles to full power. Thus, if they do not feel the reassuring tug of the wire catching the hook (more of a forward slam actually), they can just fly off the forward deck (a “touch and go”) and get back into the pattern for another try. This is known as a “bolter,” and most naval aviators make a lot of these in their careers.
Generally, hitting the rearmost (or “number one”) wire is considered dangerous, since by doing that you’re risking coming in too low and possibly hitting the stem (fantail) of the carrier (which is known as a “ramp strike”). So too is catching the last one (“number four”). Because you don’t have much room to regain airspeed in the event of a “bolter,” you risk a stall and possible crash while trying to climb back into the pattern. Catching the number-two wire is acceptable. But catching the number-three wire (called an “OK Three” by the air crews) is optimum, for it allows maximum room from the fantail and maximum rolling distance to regain speed and energy in the event of a bolter. Catching the “number three” is evidence of great professionalism and skill. In fact, if there is not a shooting war around to test your abilities and courage, then a consistent string of “OK Three” traps is considered the best path to promotion and success for a carrier pilot.
So what comes next? You have hit an “OK Three” trap, your aircraft’s tailhook has successfully caught a wire, yet you are still hurtling forward at a breathtaking speed and may fly off the forward deck edge of the “angle” at any moment if all doesn’t go well. In other words, the excitement isn’t over. Each end of the arresting wire runs though a mechanism in the deck down to a series of hydraulic ram buffers, which act to hold tension on the wire. When the aircraft’s tailhook hits the wire, the buffers dampen the energy from the aircraft, yanking it to a rapid halt. Once the aircraft stops, the pilot retracts the hook, and is rapidly taxied out of the landing zone guided by a plane handler. While this is happening, the wires are
