Comair Flight 5191

Comair Flight 5191, marketed as Delta Connection Flight 5191, was a scheduled United States domestic passenger flight from Lexington, Kentucky, to Atlanta, Georgia, operated on behalf of Delta Connection by Comair. On the morning of August 27, 2006, at around 06:07 EDT, the Bombardier Canadair Regional Jet 100ER that was being used for the flight crashed while attempting to take off from Blue Grass Airport in Fayette County, Kentucky, 4 miles west of the central business district of the City of Lexington.

The aircraft was assigned the airport's runway 22 for the takeoff, but used Runway 26 instead. Runway 26 was too short for a safe takeoff, causing the aircraft to overrun the end of the runway before it could become airborne. It crashed just past the end of the runway, killing all 47 passengers and two of the three crew. It's the second deadliest accident involving the CRJ-100/-200 after China Eastern Airlines Flight 5210 two years before. The flight's first officer was the sole survivor.
