Below are responses to mudlark's statements and questions concerning the PfT G-Forces video and the PfT/CIT video I reviewed at
http://www.ccs.neu.edu/home/will/Music/Jokes/Balsamo/balsamo2.html
I haven´t time at the moment (as you can see) to follow through this link.
Mind being a bit more specific?
Even the 1.62 G-force that was arrived at through these set of calculations, is it correct to say that the 1.62 gs was for a 4 second duration?
Yes.
If so how come the data´s highest g-force shown was 1.75g for 1/8th of a second?
Because Rob Balsamo was using data that omitted at least four of the final seconds. Most investigators had concluded that the final 4 to 8 seconds were missing. Balsamo denied that. We now know that Balsamo was wrong, because Warren Stutt succeeded in decoding four seconds beyond the end of the data that were available to Balsamo.
The last two seconds record vertical decelerations of up to 2.264g. The
average vertical deceleration for the last two seconds was 1.8g.
Had Balsamo calculated the g-load for a circular solution correctly, he'd have gotten 1.9g (for the implausible approach directly over the VDOT tower). By measuring a hockey stick curve instead of a circular arc, and by choosing three data points near the bend in the hockey stick, Balsamo calculated 10.14g. Balsamo's calculation was therefore off by a factor of 10.14/1.9, which is more than a factor of 5.
You want me to download this program or is the 4ft altitude proven at this link?
The 4 foot radar altitude is in the CSV (comma-separated values) file at Warren Stutt's web site:
http://www.warrenstutt.com/
I do not know whether Warren has yet made his data available in a more accessible form. CSV files are convenient for technical people, but I can understand why PfT/CIT cheerleaders would have trouble reading them.
In another
link I was given just tonight trying to debunk the calculations of these people just this very scenario was proposed to counterargue Rob Balsamo´s g-forces. The link actually proposed that Balsamo was sticking to the VDOT tower descent because it was the most difficult path when he was actually following the FDR data.
You don't seem to understand that the accuracy of the instruments recorded by the flight data recorder is insufficient to determine from FDR location data alone whether the aircraft flew over the VDOT tower or beside it.
Once you understand that fact, then you should also understand that Balsamo was arguing for an approach over the tallest obstacle in the area because that approach requires the highest g-forces. The more plausible approaches, with the best support from witnesses, go beside the VDOT tower instead of over it.
It was proposed that the plane actually flew over the Annex but from the other side. Which NOBODY saw.
I think you just made that up, mudlark. No sane person would propose what you just said. You certainly can't continue to cite me as the source for your mad proposal.
Balsamo found a maximum g-force of 1.4 for the NOC route using the official 540mph speed.
Rob Balsamo has made some truly batty claims, but I don't believe he has made that particular claim. I know he made no such claim in the two PfT videos you have been citing. I'd love to have a source for that claim, but once again I think you're just making it up as you go along.
This paper also says that the plane took 3.7 seconds to reach lightpole 1 and 1.3 seconds from there to the facade. If it did fly over the Annex where proposed it had a major manouevre to perform within 3.7 seconds at 540mph and get into the final 1.3 second trajectory damage ridden path.
THAT sounds like a taller order.
What sort of manouevre is necessary to fly fro NOC to the first lightpole and low level trajectory? All within 5 seconds?
It is impossible.
Agreed. No sane person would advocate a north-of-CITGO flight path that hits the light poles and then the Pentagon.
You, mudlark, are the only person in this thread who has even come close to advocating that. Your repeated attempts to give the impression that my review advocates such madness have been noted, and count only as further evidence of your desperation.
I think you missed the whole point of the reasoning behind Balsamo´s insistence on the flightpath as being over the VDOT tower and the height that he stipulated. He was going by data extracted from the FDR.
He was going by his own favorite
interpretation of data extracted from the FDR. Balsamo's interpretations have often been technically incompetent, and we now
know that these particular interpretations were based upon incomplete data as well.
Is there a layman´s version of data extracted by other parties? Pilots?
Were the altimeter readings taken into account?
Several of us have been providing details of the newly discovered last four seconds. You have dismissed some of those details out of hand within this thread, simply because they do not agree with Balsamo's incompetent calculations.
I know it has been claimed that seconds are ´missing´ but has a path been drawn or demonstrated taking in all these considerations?
The locations, headings, and lateral g-forces for the last four seconds that have just come to light are consistent with the heading implied by the path of downed light poles and subsequent impact with the Pentagon.
The altitudes and vertical g-forces are also consistent with a descent that levels off somewhat before striking the Pentagon. The pressure altitudes recorded are not entirely consistent with the radar altitudes and vertical g-forces, but that is not terribly surprising because the aircraft was being operated well outside the parameters for which the pressure altimeter was designed and calibrated.
