"Pilot errors caused the deadly crash of a commuter airliner in northeast Missouri in 2004, and the crew's nonstop joking and expletive-laden banter in the cockpit didn't help, federal investigators said Tuesday. The two-man crew and 11 of 13 passengers were killed when Corporate Airlines Flight 5966 crashed on Oct. 19, 2004. It was the country's deadliest civilian air crash that year."
