Swept Wings and Yaw Dampers

 

The introduction of swept wings introduced a new problem - Dutch Roll, a combination of periodic roll and yaw. This problem requires a yaw damper , an automatic device that operates the rudder to counter act Dutch Roll. Is this effective at speeds well above VNE ? Probably not. Another reason why the fictitious "UA 175" would have been uncontrollable.

Commercial Pilot

 

I qualified as a commercial pilot in 1995. I did my test on a Beech Duchess twin . This plane had a good autopilot and had weather radar. However I was completely unaware that modern jetliners were equipped with yaw dampers or even that yaw dampers existed. More proof that private pilots could not have accurately flown jetliners to their destinations and then achieved unprecedented sea level speeds while in perfect control, aiming at narrow targets barely wider than the aircraft and scoring perfect hits on both occasions.

No Witnesses yet

 

I will be periodically renewing my invitation to witnesses or those who have met witnesses. Or even those who have met someone who in turn has met a witness.

If Planes had crashed into the twin towers

 

There would have been huge tail sections on Liberty street. Large twisted wing sections. Bodies, some strapped into their seats. Pools of flaming jet fuel. None of this was photographed. The perpetrators guessed the sheeple would swallow the absurd premise that the entire fragile airliners and their contents were swallowed by the buildings. The controlled "truth" movement was cleverly put in place and instructed to exclude and ridicule those who pointed out the absurdities in the planes hypothesis. Thus the Zionist media, the primary promoters of this vile false flag, were protected and their credibility retained intact. Amazing.

Air Density

 

The reason that cruising air and ground speeds are not attainable at sea level is due to air density variation with altitude. The density of air at a typical cruising altitude of 35,000 feet is about one third of the density at sea level. The Zionist media brazenly claimed that the late  "UA 175" was moving at 546 mph before it rolled to the left and vanished into the massive steel façade of the South Tower.

Box Cutters

 

When I was about 30 years old I was confronted with a fellow with a knife on a dark deserted beach. I weighed the situation and then charged in to tackle him. He turned tail and fled. How extremely unlikely it is that 8 beefy airline pilots all decided to cravenly hand over their controls to physically unimpressive hijackers armed only with miserable little box cutters.

Thin Shell Buckling

 

Timoshenko's formula for thin shell buckling can be used to demonstrate that the fuselage would crumple like a coke/beer can on impact. Fuselage panels are constructed of 1 mm thick alclad (plated duralium alloy).

Shearing

 

It can be demonstrated with simple but irrefutable computations that each perimeter column (77 per side of each tower) had the strength to shear off a B767 wing quite close to the root.

 

A B25 bomber hit the Empire State Building in a July 1945 accident. Both wings were sheared off . One fell on to the steps on the side of the building, the other to the street below. Photographs exist of the mangled but still recognisable wing that hit the street.

It is well over a month since I last issued an invitation to witnesses. "UA 175", anyone ?

UA 175

 

The late "UA 175" will fascinate me as long as I live. Imagine the power of a propaganda machine that plant in the mind of all mankind a piece of fake history. An event that did not occur in peak hour in one of the world's biggest cities in front of numerous television cameras has become accepted as real history. Synthetic Reality created in real time. Amazing.

Nico Haupt

 

I should take a moment to mention Nico Haupt. This guy was a prominent No Planer with at least one web site. He was arrested at a demonstration about 2010. He has not been seen or heard from since. He has been swallowed into an information black hole. Or worse. RIP Nico if Mossad or the CIA liquidated you. It can be dangerous to be a No Planer. Researcher Gerald Holmgren died suddenly of cancer at age 52 many years ago. He was frightened before that and pulled all his work off the net.

Joseph Keith

 

Another forgotten truth hero is senior aerospace engineer Joseph Keith. He first used both the sentences in my signature. He also spoke of the absurdity of cruising speeds at sea level and how the engines would react.

Roll Rate

 

This is one area which no one no one except myself has gone. Aircraft turn by banking. You bank by turning the control wheel or stick in the direction you want to bank. The ailerons on the wing trailing edges move up on their hinges on one wing and down on the other wing. In a turn to the right the right wing ailerons go up and the port or left wing ailerons go down. The right wing generates less lift , the left wing generates more lift and the aircraft banks to the right and turns to the right. Aileron position determines rate of roll. You neutralise ailerons when you attain the required angle of bank and the aircraft continues turning until you return it to level by turning the control wheel in the opposite direction. Bank angle recommended for general aviation (light) aircraft is 30 degrees. On passenger jets a bank angle of 20 degrees gives you a rate one turn if you are flying  "clean" (that is flaps and landing gear retracted) and at an airspeed of 200 knots. A rate one turn returns you to a reciprocal heading in one minute. I won't go into differential ailerons, use of slats in passenger jets and so on. Rate of roll determines how long it takes to achieve the desired angle of bank. A roll rate of 5 degrees per second means you achieve a 20 degree angle of bank in 4 seconds. I have on numerous occasions timed jetliners bank and it is always 4 to 5 degrees per second.

"UA 175"

 

"UA 175" on the contrary was rolling at 27 degrees per second into it's final turn. We must recall that at the impossible speed of 546 mph the outboard ailerons and slats were locked out and all this fictitious aircraft had were inboard ailerons blown down to their limits. My own calculations using Prandtl's lifting line method suggest an airliner in the best of circumstances can only roll at about 8 to 10 degrees per second.

27 degrees per second

 

I estimated "UA 175's roll rate from a (fake) video filmed from Brooklyn.
