Around this time (roughly), the FAA tells the White House that it still cannot account for three planes in addition to the four that have crashed. It takes the FAA another hour and a half to account for these three aircraft. [Time, 9/14/2001] Vice President Cheney later says, “That’s what we started working off of, that list of six, and we could account for two of them in New York. The third one we didn’t know what had happened to. It turned out it had hit the Pentagon, but the first reports on the Pentagon attack suggested a helicopter and then later a private jet.”
[Los Angeles Times, 9/17/2001] Amongst false rumors during the day are reports of a bomb aboard a United Airlines jet that just landed in Rockford, Illinois. “Another plane disappears from radar and might have crashed in Kentucky. The reports are so serious that [FAA head Jane] Garvey notifies the White House that there has been another crash. Only later does she learn the reports are erroneous.”
