In 1993 Druyun was investigated for her involvement in a plan to speed up payments by the Air Force to McDonnell Douglas. Although dozens of other people involved were convicted or discharged, Druyun kept her position. In 2000 Druyun sent the resumes of her daughter, a recent college graduate, and her daughter's fiancé, a published PhD Aeronautical Engineer, to Boeing, which had merged with McDonnell Douglas in 1997, and both were hired.
U.S. Air Force tanker contract controversy
In May 2003, the United States Air Force announced it would lease 100 KC-767 tankers to replace the oldest 136 of its KC-135s. The 10-year lease would give the USAF the option to purchase the aircraft at the end of the contract. In September 2003, responding to critics who argued that the lease was vastly more expensive than an outright purchase, the United States Department of Defense announced a revised lease. In November 2003, the Air Force decided it would lease 20 KC-767 aircraft and purchase 80 tankers. After leaving the Air Force in 2003, Druyun took a job with Boeing at an annual salary of $250,000. She also received a $50,000 signing bonus. In December 2003, the Pentagon announced the project was to be frozen while an investigation of allegations of corruption by Druyun was begun. Druyun pleaded guilty to inflating the price of the contract to favor her future employer and to passing information on the competing Airbus A330 MRTT bid. CBS News called it "the biggest Pentagon scandal in 20 years" and said that she pleaded guilty to a felony. In October 2004, Druyun was sentenced to nine months in federal prison for corruption, fined $5,000, given three years of supervised release, and 150 hours of community service. She began her prison term on January 5, 2005 as inmate number 47614-083. She was released from prison on September 30, 2005. The scandal led to the firing of Boeing CFO Michael M. Sears and the resignation of Boeing CEO Phil Condit. On February 18, 2005, Sears was sentenced to four months in prison. Boeing ended up paying a $615 million fine for their involvement. According to The Federal Times, Druyun will still be receiving a federal pension. Druyun was also found guilty in awarding the initial Small Diameter Bomb contract to Boeing. Donald Rumsfeld stated that he was told that "what she did was acquire a great deal of authority and make a lot of decisions, and there was very little adult supervision".
