Transcription, 0830-0835. The second statement in the transcription at 3:34 [3:44] appears erroneous: “A B-52 on a TA calibration check to rw [runway] 11 [110-degrees heading southeast] requested clearance to WT at FL200.” Conversely, also at 3:34 [3:44], the first communication between Runyon and controller indicates the B-52 is actually on low approach over runway 29 [290-degrees heading northwest]. The acronym “TA” is unknown. It may refer to transition altitude, or Terrain Avoidance System, which provides an aircraft with a situation display of the ground and obstacles so that the pilot can maneuver the aircraft to avoid the obstruction.
