According to CBS News, crew acknowledged clearance for 22. Orr (referred to below) is a CBS Correspondent.
A little after 6 a.m., flight controllers gave the pilots clearance to take off from runway 22 and the pilots acknowledged the controllers with a "roger," Orr reports. However, it appears the pilots took off from runway 26, which is only half the size of the 7,000 foot runway 22.
Sources tell Orr the radar tape and debris from the crash site suggest the plane never got airborne, that instead it went off the end of the runway and through a retaining area before settling into the crash site where it seems a significant post-crash fire erupted.
Orr adds that two flights took off from the correct runway (22) just prior to the Comair flight's departure.
