An interesting problem that came up during development of the Navy version, which has to land on carriers: when the landing gear and hooks were first tested, the placement of the back wheels was such that they created a sine wave in the arresting cable which just happened to be "down" when the hook moved over the cable, meaning the hook wouldn't catch and the plane could never land this way. They then had to go back and redesign the arrangement of the landing gear and hook.
