When landing on aircraft carriers, a tailhook is used to snag one of the cables on the carrier deck, which slows the aircraft.
When the landing gear fails to deploy I have seen it is possible to make an emergency landing by landing on the belly - and I'm sure there are other options too.
However, what would a pilot do if the tailhook failed to deploy when landing on a carrier? Is the carrier deck long enough for a pilot to stop without the tailhook? What else could a pilot do in this situation?
