F9F Panther Catapult Hook Up

The F9F Panther's catapult hook was retractable and located in the "notch" between the aft end of the speed brakes.

It can just be seen in this photo between the heads of the sailors hooking the pendant to it.

The holdback was attached to a retractable hook on the belly aft of the main landing gear.

Put it all together...
