It happened again on Wednesday, December 9, 2009, less than a month after the incident aboard AirTran Flight 297. United Airlines Flight 227, scheduled to depart Denver International Airport at 1:50 pm Wednesday for Los Angeles was disrupted when several passengers who were described as Middle Eastern in appearance, confirmed by this investigator to be a group of Muslims traveling together, were removed from that aircraft due to suspicious behavior that originated in the terminal and continued to the airplane.
