If I'm following it correctly, the tower told the small plane to enter the runway and take a position prepared to take off. "N409DR, Charlotte tower, 18L position and hold, traffic landing 23" tells the small plane to get on runway 18L and hold position (I think) and alerts the pilot to traffic on the other runway. Right after telling the bluestreak plane to take off using the same runway. I wish there was a timestamp to queue up that part, It's fairly close to the end.
