From the Intro:
“The title of this photobook, “99 Camelots”, is not a reference to any specific number of Tomcats. Rather, the “99” is a blanket radio call which would cover a specific group of aircraft, in this case our VF-14 Tophatter jets. “99 Camelots, charlie on arrival” would be the radio call from our ready room to all our airborne aircraft that they can expect to land on the carrier as soon as they arrive at the ship vice holding overhead.”
