I found what appears to be Flight Manifests. Lots of codes I don't understand. These come off of a list called, ON LIST and CANCELLATIONS, dated OCT 2, 2001.
Under PNR I see various codes, such as CUFWSG and HKGTVB.
On this list they have a column called CONFIRMED. Interestingly only the hijackers' names are YES confirmed.
Any assistance navigating this maze would be greatly appreciated.
