I've found the ATC recording:

Starting at 2226:40Z, the Cherokee is cleared for takeoff, with a southbound climb out. Subsequently, a Boeing test flight calls for takeoff and is told to lineup and wait, due to the Cherokee departing from an intersection. The Tower then asks the Cherokee to make a right turn out, to allow the Boeing to take off. While the Tower is giving the Boeing takeoff clearance, there is another transmission, that might have been from the Cherokee. Unfortunately the recording stops there and the next half hour from 2230Z is not available.
