All planes aren't real

Eyewitnesses

"I never actually saw a plane hit the building. I never saw that. I saw it on television, but I never saw it while I was standing there."

---Stephen M. Gregory, retired New York Fire Department Assistant Fire Commissioner

“I did not see a plane go in, that just exploded.”

---ABC reporter Don Dahler

It is a myth that thousands of people actually saw a plane. Surrounded by tall buildings few people in New York’s business district actually had a decent view of the WTC towers. Few people reported actually hearing and seeing planes. Most testimonies of those who did are inconsistent with that of a wide-body commercial airliner hitting a building at 800 feet altitude, full throttle. Meanwhile, it was a simple matter for the TV networks to keep the eyewitnesses who didn’t see a plane off the air. A very small percentage of the approximately 500 First Responders at the WTC reported seeing commercial airliners. An even smaller number reported hearing them. A jet plane takeoff at 300 feet altitude is 10 times louder than a rock concert. There are witnesses who saw the South Tower explode but did not see a plane strike the tower.

“The closer you were, the less you knew.”

---Police Chief Joe Esposito, NYPD

“It was almost like the closer you were, the less you knew…As we look back, we were the least informed.”

---Battalion Chief Joseph Pfeifer, FDNY

Survey results of 117 witnesses

• Only 19 of the witnesses near the WTC reported actually seeing plane 2 before impact and, as a percentage of total number near the WTC, this was 20%.
• Only 20 of the witnesses near the WTC reported actually hearing plane 2 before impact and as a percentage of total number near the WTC, this was 21%.
• Only 8 of the witnesses near the WTC reported actually seeing and hearing plane 2 before impact and as a percentage of total number near the WTC, this was 8.3%.

TV > Real Life.

Hundreds of people saw it happen in person, but billions saw it on TV. The Mandela Effect can explain why a few witnesses remember, years later, seeing the plane in person. It's just like those people who "remember" seeing the (non-existant) footage of Tank Man getting crushed by the Chinese tanks.

What about all the videos of the plane?

Ace Baker has a good video on the capabilities of live video compositing.

Irregularities and clues in the footage

1. Chopper 5 footage appears to show a mistake in live video compositing and attempts to correct the mistake. As shown in Ace Baker’s video, it looks as if the layer mask slipped a little to the left and allowed the nose of the plane to peak through to the other side. This was followed by a sudden cut in the video feed that was likely deliberate and not the result of a lost connection, as if the error was noticed.

2. The plane clips into the tower without causing any visible destruction to the tower, or itself crumpling, until after it disappears completely, and then an explosion emanates from within.

3. No wake vortex. Airplanes are trailed by a column of moving air which takes minutes to dissipate. In no footage will you see any disturbances in the smoke cloud.

4. No flexing or bending of the wings. It's been debated whether the aircraft could even travel at 200 mph above its maximum operating velocity without its wings breaking into pieces, but assuming it could do so it would be shaking and bending violently, but in the videos it's always completely rigid.
