Thanks, Mods if you are able to do this.
There's enough confusion in the thread already, without a Gage-bot sent in to advertise his message.

His power point presentation proves without a shadow of a doubt the buildings were brought down with explosive thermite. His proof is irrefutable.

Hey trebor/Pinch/William Paisley,
How did it feel to get spanked by Kolstad via email? Yes, I saw the emails, typical trebor/Pinch/Will Paisley. A person who never amounted to anything but a RIO and never made it to Top Gun. To top it off, a civilian washout.

Your pompousness is noted. May I suggest you read the works of Tony Szamboti. Unlike you, he is a structural engineer. If or when you graduate from college maybe have a discussion with him or Richard Gage or the other 5000 members of AE911truth. Until then, it best you keep your opinions to yourself. you only make yourself sound foolish.

Maybe you should educate yourself on thermite before you act all haughty. Tony and Richard know thermites power. Maybe you should have the guts to contact them. Maybe you'll learn something.

911Files is one of those rare "Truthers" who feel there is a conspiracy within a conspiracy. He follows the lead of a janitor better known as, and appropriately named, "Caustic Logic".
.... and they call us nut jobs. lol... too funny.
You have a few questions that are unanswered and you doubt the NTSB data, but you claim that you're not a truther even though you ask questions like you are one. How does that work?

4. You can use the radar height to get the best possible INDEX of all data, since it is provided at 8 Hz. Match it to the terrain.

5. You can calculate the second by second vertical velocity by using "difference methods" on the Pressure Altitude (PA).

You'll note that all those circle & hyperbolic profile assumptions are wrong. As is the assumption that the plane had to EVER "level off". It appears that it did not.

of what I've got so far:

With several of us using different methods to perform the
calculations independently, we'll get better checking of our
results than if we were all using exactly the same methods.
Some methods may be more accurate than others, but all should
show a similar general picture.

I notice the RA diverges from PA (raw), which compares with my study, but I must be reading the 'true altitude' (RA corrected for terrain elevation) wrong since it tends to diverge as well. I am getting the opposite result, with 'true altitude' (RA + elevation) converging wth PA at the end-of-file (EOF)

Since there is a known offset in the INS data (~0.2 nautical miles), I found the lowest elevation within the 2 sigma radius of the RO position and used it as a lower bound for terrain elevation. Similarly, the highest was used for the upper bound. The difference between 'true altitude' and the raw PA is plotted for both upper and lower bounds and linear trend lines calculated. For both, the trend is convergence at the EOF.
In other words, the difference between PA and true altitude was ~275 feet at 16 seconds before impact, and decreased to ~135 feet by the last subframe (as elevation decreased and speed increased). As expected, there is an anomalous bump at -3 and -4 seconds (using your scale) as the plane passed over the Annex area structures.

Having said that, I have a few questions for those still refuting the
"Pressure Altitude Error". Now that we know that PA is measured using an
electric sensor (absolute pressure sensor) via the Air Data Computer [ADC],
and not a mechanical standby device, please explain the following:
Originally posted by turbofan
1. PA is measured by the Air Data Computer which also supplies the
vertical speed. Both of these measurements are derived using the same
pressure sensor (PA is absolute; Vertical Speed is the rate of delta in altitude).
If PA is considered to be in error, how can you believe the Vertical Speed?

2a. If the wing span of the 757-200 can barely reach the camera mast and
pole #2 with an approximate 61 degree angle, explain the gross bend in
pole #2 and why it was not carried forward in the direction of force (flight)?

You don't have to put your money on this, just have a look at vertical speed
for that segment of PA.
Surely if this was a real flight, or flight sim. the VSI and PA will relate in
proportion as they use the same sensor to produce their values.
