1. Slides for: Towards a Comprehensive 9/11 Conspiracy Theory: The “All Hijacked Passengers Survived” Hypothesis David L. Griscom, Ph.D. Research Physicist, retired from The Naval Research Laboratory, Washington, DC 1 December 2009 N.B. As of this date, the following slides are intended as a companion piece for a Microsoft Word text document of the same title (but different file name: “A New 911 Hypothesis v12”) rather than as a free standing presentation. The slide numbers referred to in that text document are indicated in the upper left-hand corner of the following slides. If one should choose to look only at these slides (and not the text), the first four following this one represent an earlier hypothesis (now regarded as faulty) for the attacks on the World Trade Center having been perpetrated by U.S. conspirators with access to Air Force bases, aircraft, and facilities for modifying aircraft into pilotless drones. I subsequently concluded that the 605-mph dive of the aircraft believed in my earlier hypothesis to have been United Airlines Flight 175 was unlikely to have been survived by a Boeing 767. In addition, after closer inspection of the amateur films cited in the text document, I concluded that the aircraft that made this dive was (were) much smaller than a 767. For reasons explained in the Word doc, all versions of the present hypothesis have continued to assume that all four airliners allegedly hijacked on 9/11 were flown by the conspirators themselves and therefore that (1) they did not crash and (2) their co-conspirator passengers all survived (and any innocent passengers were murdered). Thus, slides 5 and 6 are intended to replace slides 3 and 4, respectively, in order to illustrate the current version of my conspiracy hypothesis, which allows UA-175 to land at a normal safe speed. Still, this hypothesis is subject to further changes if and when other factual considerations compel such revisions. --D.L.G.

3. NTSB: AA-11 Radar Ground Track The Drone, likely an A-3 (smaller than but resembling a Boeing 767) Strikes the North Tower Hypothesized Continuation of AA-11 to Griffis AFB Hypothesized Substitution of Drone Attacker

4. NSTB: AA-11 Altitude Profile Present Model Interpretation: Eastern Daylight Time (hh:mm) Altitude (feet) Drone Climbs out of Griffiss AA-11 Descends to Griffiss Transponder Turned Off AA-11 Drone(s) Cross Ground Track of UA-175

5. WTC South Tower Struck by a Drone Launched from McGuire AFB Standing Hypothesis: NTSB: UA-175 Radar Ground Track UA-175 Pulls out of Dive, Circles WTC, and Heads for McGuire AFB Early Hypothesis, Now Rejected: Drone Boeing 737 Launched from McGuire AFB

7. Time increasing during the 7 th second of this video. Begin 8 th second. Jetliner about to strike WTC2 Fast object pulling out of dive The fast object circled in blue moves right to left 12 times its apparent length in slightly less than 1 second. If this was an F-16 fighter (length 59 feet), its lateral speed was greater than 470 mph, but because it disappears in the distance at the same time, its ground speed is likely greater than 660 mph.

8. Fourteen Seconds after the Strike on WTC2, this Object Passes from West to East in Less than One Second! Could this be the same “bird” that pulled out of a dive over near the Jersey Shore at the very same second the Boeing struck the South Tower? Well, the shortest distance from the Twin Towers to the Jersey Turnpike was 2.15 miles, and to fly that course in 14 seconds would require a straight-line speed of 553 mph. Were these birds? You be the judge.

10. Amateur video footage of the 9/11 attack on World Trade Center 2 that captures additional flying objects moving across the screen faster than the Boeing 767 (which has been clocked as approaching at speeds ranging from 500 to 574 mph). This particular copy is the best preserved one that I’ve been able to find on the internet... since many have been taken down by hackers, and the rest have been modified... to make them look as though the fast objects are birds! As will be seen below, this video was taken from a car approaching the Brooklyn Bridge. The New York City Hall will appear just around the corner as the car in which the cameraman is riding moves westward toward the Brooklyn Bridge. This is the top of the guard rail of the Brooklyn Bridge.
