Colgan Air was an American certificated regional airline subsidiary of Pinnacle Airlines Corp. The headquarters of Colgan Air were located in Memphis, Tennessee. Colgan Air operated for Continental Express/United Express, and US Airways Express before it became defunct. Pinnacle Airlines Corporation phased out the Colgan Air name on September 5, 2012, and transferred personnel and logistics to Pinnacle Airlines. History Charles J. Colgan founded fixed-base operator Colgan Airways Corporation at Manassas Airport in 1965. It began scheduled service under contract with IBM in 1970 between Manassas, Virginia, near Washington, D.C., and Dutchess County Airport near Poughkeepsie, New York. In 1986 Colgan Air received its first airline contract with New York Air operating as New York Air Connection with Beechcraft Model 99's, Beech 1900C's, and Shorts 330's. New York Air was merged into Continental Airlines on February 1, 1987, at which time Colgan became a Continental Express feeder carrier. Jetstream 31 aircraft were then acquired. In 1986 and 1987 Colgan also code-shared with Pan Am as a Pan Am Partner on the Washington Dulles to Norfolk route. Colgan later sold to Presidential Airways which was also a Continental Express operator. In mid 1988 Colgan and Presidential switched from a Continental Express feeder to become a United Express feeder carrier. This operation under the United Airlines banner also only lasted about one year before Presidential shut down in 1989. After Presidential went defunct, Colgan and his son, Michael J., restarted service under the name National Capital on a Washington-Dulles to Binghamton, NY, route on December 1, 1991. Service was provided with Beechcraft 1900C equipment. .This route was later dropped and the name Colgan Air adopted. On July 1, 1997 Colgan became a feeder for Continental Airlines once again, this time operating under the name Continental Connection. On December 11, 1999, Colgan left the Continental system and became exclusively a US Airways Express carrier, focusing its routes around major US Airways stations such as LaGuardia, Pittsburgh, and Boston. However, in 2005 Colgan acquired additional Saab 340 aircraft and resumed service as Continental Connection out of Houston. Early on the morning of September 11, 2001, al-Qaeda affiliated hijackers Mohammed Atta and Abdulaziz al-Omari flew Colgan Air Flight 5930 from Portland International Jetport in Maine to Boston Logan Airport in Massachusetts, where they went on to board American Airlines Flight 11. On October 4, 2005, Colgan Air started providing flights for United Express flights out
