In 1978, a ruling by the Civil Aeronautics Board allowed Federal Express to purchase larger aircraft. Federal Express's options included 20 Boeing 727s that United Airlines was retiring and/or the French-built $$$ Fanjet Falcon 20.

• ? Boeing 727 Falcon 20
Direct Operating Cost SI400 per hour $500 per hour
Pa>load -12.000 pounds 6000 pounds
Federal Express was raced with the following constraints:
• Hourly operating cost was limited to $35,000.
• Total payload had to be at least 672,000 pounds.

Three years later, the job market for the Class of 2003 was rather different. U.S. economic growth had slowed to a crawl, and then to a halt.
