United Airlines Flight 696: United Airlines Flight 696 was a flight from San Francisco International Airport in San Francisco, California, to Seattle, Washington, with 75 people in board.  After takeoff from San Francisco, Clay Thomas hijacked the Boeing 727, demanding the plane land in Oakland, California, and fuel up for a flight to Cuba.  The crew negotiated the release of all the passengers and cabin crew while on the ground in Oakland waiting for fuel.  Panicked by the sight of police vehicles, Thomas cut the fueling short and demanded an immediate departure to Cuba.  Once the plane was airborne, the pilot explained that the aircraft still did not have enough fuel to reach Cuba, and Thomas agreed to land in Denver, Colorado, for more fuel.  About 90 minutes after landing, the three members of the cockpit crew all jumped to safety from the open cockpit windows, all suffering injuries in the 18-foot (5.5-meter) jump.  Within five minutes of the escape and without hostages, Thomas meekly surrendered to the U.S. Federal Bureau of Investigation.  Thomas is currently incarcerated in a mental Institution in Colorado.

Prime Airlines: Prime Airlines was formed by HeavyLift Cargo Airlines (HC Airlines) as a passenger charter carrier.  Initially offering its sole aircraft on an ad hoc basis from its base at East Midlands Airport (EMA) near Nottingham.  Originally the airline was to be called Breeze but the company had difficulties in securing the name for operation.  Finally the name Prime Airlines was chosen.  With the assistance of former Transaer managers HC Airlines leased its sole aircraft an A300B4-203 and recruitment began for cabin crew.  As the airline only had one aircraft a total of 27 cabin crew were hired for the start of operations in mid-2001.  The company had no need to recruit flight crew as HC Airlines operated the Airbus A300B4 in cargo configuration and simply cross utilized the crew.  Once the airline obtained its AOC it began operations for a number of British inclusive tour operators and the military flying to destinations around Europe and the Middle East.  After 9/11 the company suffered with lack of contracts and a second blow came when an American Airlines Airbus A300 (Flight 587) crashed in New York City.  Like most airlines at this time Prime had to make redundancies and cut its cabin crew numbers in half.  The start of 2002 looked better for Prime Airlines as once again ad hoc charter contacts came in.  The company started to plan for a brighter future and looked at adding extra aircraft to its fleet.
