Project Firefly

Secret Service Agent H. Hunter Mahoy interrogates an intruder caught climbing the White House fence. He learns that in two days' time, a top-secret aircraft prototype, code-named Project Firefly, is to be stolen during its maiden flight. The nuclear-powered 747 jumbo jet has endless range and almost unlimited capacity to remain aloft without the need to refuel. It also carries the latest airborne defense systems of the United States.
President James Weber immediately dispatches Hunter, along with two additional F-15-E escort fighter jets, to accompany Firefly to Edwards Air Force Base in Southern California.
That same evening, the president's daughter, Kate Weber, is kidnapped in a volley of gunfire: her Secret Service detail lie wounded or dying.
Daily photographs of Kate are sent to a Washington Herald reporter, Morgan Lindsay, who witnessed the abduction.
Firefly disappears despite all the precautions as Hunter and all four escort fighters fall out of the sky over the snow-covered Sierras.
Hunter's fellow agent, Charles Minsk, is in contact with Search and Rescue and with the intelligence agencies. Time is slipping away, so Morgan and Charles join forces to find their friends and the atomic Firefly.
