Extra Passenger on Flight 93-- Extra Passengers on All the 9/11 Flights?

While googling flight 93 and the 9:16 am time for the suspected hijacking, I came across this strange site: http://www.cyberspaceorbit.com/warrant21.htm

The site is a little out of date, and seems to be a random collection of various articles and observations, some of which deal with 9/11.

In any case, in the middle of the page was this interesting tidbit:

An acquaintance of mine, with top classified clearance, runs a training program for special forces for the military and police professionals worldwide. On flight 93, one of their highly trained judo instructors died. He was a professional special forces warrior, yet his name is nowhere to be found on news releases. It is highly unlikely that he was there for a pleasure ride.

I will assume this is legit for two reasons. First, there is no strange conspiracy attached to it, it is merely a random observation on the page. Second of all, it makes a lot of sense.

Undoubtedly, there were a set of such people on each flight, as part of the back-up plan for Operation Vigilant Warrior/Vigilant Guardian. In other words, these guys were part of the hijacking drill. Such a person was known to be on flight 11, as well-- Daniel Lewin:who once belonged to the Israel Defense Force, Sayeret Matkal, a top-secret counter-terrorist unit.

Moreover, these special forces agents could be why the number of people who were reported to have died on each plane was greater than the number of names of the passengers reported by the media, even when the hijackers are taken into account*. This fact has been analyzed by several 9/11 sites. And now it makes sense-- the airlines didn't report the names of the special forces agents on each flight, because that would be a dead give-away for what was happening on 9/11.

Thus, this little 9/11 mystery of the numbers of passengers is a mystery no more.

for instance, from 911timeline.net--

7:59 a.m.: American Airlines Flight 11 a Boeing 767-223ER with a maximum capacity of 181 passengers and 23,980 gallons of fuel, lifts off from Logan International Airport in Boston, Massachusetts, bound for Los Angeles International Airport in Los Angeles, California. Take-off was scheduled for 7:45. There are supposed to be 92 victims on board American Airlines Flight 11, yet when you add up the official death manifest list that was published on CNN.com, there are only 86 victims.

The same goes for the other three flights of September 11th. Add up the passenger and crew lists from all 4 flights of 911 and you have officially 266 people on board. Yet when one adds up the 4 official death manifest lists published on CNN.com, there are only 229 names. Somehow 37 people are missing from the 4 CNN.com official death manifest lists, including all 19 of the hijackers. There is not even one Arabic name there. Why?

One other thing; CNN.com says there are 45 fatalities on United Airlines Flight 93, others say there are 44. This would make 36 missing, and 265 deaths for all 4 airliners.
