Part 3/8:
A central theme of the presentation revolves around the confusion between Delta 1989 and Delta 89. Both flights were in close vicinity around the same time, and both were associated with hijacking reports. However, crucial differences persisted:
Call Signs and Flight Paths: Delta 1989 had a designated flight plan to Los Angeles, while Delta 89 was reported to be heading towards Las Vegas with an unusual squawk code of 7112, indicating a possible hijacking.
Radar Identification Issues: The discussion emphasized the limitations of NORAD’s radar systems compared to the FAA’s more modern equipment. This lack resulted in the early identification challenges that led to miscommunication among air traffic control.
