"We Have Some Planes"
The 9/11 Commission's Report provides an almost visual description of the Arab hijackers. It depicts in minute detail events occurring inside the cabin of the four hijacked planes.
In the absence of surviving passengers, this "corroborating evidence", was based on passengers' cell and air phone conversations with their loved ones. According to the Report, the cockpit voice recorder (CVR) was only recovered in the case of one of the flights (UAL 93).
Focusing on the personal drama of the passengers, the Commission has built much of its narrative around the phone conversations. The Arabs are portrayed with their knives and box cutters, scheming in the name of Allah, to bring down the planes and turn them "into large guided missiles" (Report, Chapter 1, http://www.9-11commission.gov/report/911Report_Ch1.pdf ).
The Technology of Wireless Transmission
The Report conveys the impression that cell phone ground-to-air communication from high altitude was of reasonably good quality, and that there was no major impediment or obstruction in wireless transmission.
Some of the conversations were with onboard air phones, which contrary to the cell phones provide for good quality transmission. The report does not draw a clear demarcation between the two types of calls.
More significantly, what this carefully drafted script fails to mention is that, given the prevailing technology in September 2001, it was extremely difficult, if not impossible, to place a wireless cell call from an aircraft traveling at high speed above 8000 feet:
"Wireless communications networks weren't designed for ground-to-air communication. Cellular experts privately admit that they're surprised the calls were able to be placed from the hijacked planes, and that they lasted as long as they did. They speculate that the only reason that the calls went through in the first place is that the aircraft were flying so close to the ground ( http://www.elliott.org/technology/2001/cellpermit.htm
Expert opinion within the wireless telecom industry casts serious doubt on "the findings" of the 9/11 Commission.
