Catching the number 4 wire at the TR. Aircraft usually go for the number 3 wire. Pilots are aiming for that wire, as it is the safest/most effective one. They never aim for the 1st because that one is dangerously close to the edge of deck. If they come in too low on the 1st wire, they could easily crash into the stern of the ship. It is acceptable to snag the 2nd or 4th wire, but for a pilot to move up through the ranks, he/she has to be able to catch the 3rd wire consistently. In the squadron room the achievement of each pilot is logged, catching too many times the wrong ones cost you beers
