I’m not sure that comparison is accurate.
FedEx and WGA did not have access to the same information UPS did at the time. UPS had immediate access to frame-by-frame, high-definition video of the takeoff sequence from its own cameras, captured moments after the event. Yet, they still decided to let the MD continue to fly. Even on the day of the crash.

FedEx and WGA made their decisions without that level of detail. In fact, many of us were surprised when the NTSB’s first preliminary report revealed that the source of the frame-by-frame takeoff footage was UPS.
