the planes were fitted out with drone tech and flown remotley.

Q) Could pilots with a commercial licencse have hit the the World Trade Center and the Pentagon with a 767 or 757 at the speeds observed on 9/11? (the pilots were assumed to have earned a commercial license within the previous year) (Tower #1 = 473 - 510 Knots Groundspeed, Tower#2 = 430 Knots Groundspeed, Pentagon = 460 Knots Groundspeed)

1) Yes
2) Yes, it would be fairly straightforward
3) Yes, but it would have needed a lot of concentration
4) Yes, but it would have been very difficult
5) Probably, but they were pretty lucky
6) Probably not, it would be very hard to do
7) No
8) No, the plane would be impossible to control at that speed
9) No, the plane would have fallen apart at that speed
10) No, the plane could never even reach that speed.
11) I don't know

A short lesson on "Ground Effect"



We've been told that as the 757 approached the Pentagon, the aircraft was flying EXTREMELY low to the ground, low enough to take down light poles on the nearby freeway, at 500+ MPH.

No attempt has been made to explain how the pilot managed to overcome the exponentially increased lift on the aircraft's wings caused by ground effect.
 Quoting: Anonymous Coward 33832742


Question can ground effect be overcome at 500 mph..?

I AM a pilot.

Not a 757 pilot, just a private pilot. 157 hours in Cessna 172s. (100 more hours than the "9/11 hijackers")

I couldn't fly a 757.

I won't even get into the hilarity of the boxcutter knife thing.

Okay. These guys just did the hijacking thing, they just slashed the throats of two pilots, blood squirting out all over the place, blood all over the cockpit, all over themselves, they're all pumped up, feeling the adrenaline rush, and now they have to sit down and figure out what all that newfangled glass cockpit stuff is all about.

They're transitioning from six steam gauges in a single engine 100 kt prop job, to a 21st century glass cockpit multi engine jet. In a matter of a few minutes. At 493kts. And they're covered in someone else's blood.

With their heart rates going at 150 beats per minute.

I did quite extensively.

For just about every commercial airliner of that time enthusiasts made extremely detailed flyable models of those aircraft. They had all the panels. All the switches were operable including radios, nav equipment, and autopilots. All the gauges worked, all the warning devices operated.

Now as far as what exactly happens at overspeeds?

You don't have much data to go on as pilots wouldn't admit that they did it.

My take?

Flying the simulators I saw no loss of control at all at overspeeds.

In fact it is difficult to NOT overspeed at altitudes under 10,000 feet. You have to have the throttles way back if you are coming down.

Since nobody has flown a 757 at overspeeds at low altitude to the point of failure of the airframe...

all you have is CONJECTURE as to when and if it would happen.

The aircraft are built with a HUGE safety factor engineering wise.

I would say they will pull at least 5G+ and 3G- with no problems whatsoever. And that is a hell of a lot more stress than flying at subsonic overspeeds for a few minutes.

OK...

The alleged hijackers (who later turned up very much alive) weren't flying a Microsoft flight simulator. They were flying a Boeing 757.

A real one.

Have you ever flown a real aircraft? Go out to your local flying school and hire yourself a flight instructor and a Cessna 172 for a few hours, and then come back and tell us what you've learned.

Microsoft makes an excellent simulator, but that's what it is. A simulator. It's not the real thing, in the real world.

Lacy says he's done many things that didn't actually "advance aviation," but were a lot of fun. His experience during the Mojave 1000 with daredevil Rick Rojatt, aka "The Human Fly," a Marvel Comics character, falls under that category. The stunt performer, intent on proving he was the "greatest superhero that ever lived," put his life in capable hands when he flew above the Mojave Desert on top of a DC-8 piloted by Lacy.

"We made a mount for him," said Lacy. "He couldn't have gotten off if he wanted to. He always told people he was up there at 300 mph, but we never flew that fast. The fastest I ever flew him was 220 knots, once, just for a short burst. Most of the time, we were flying at 175 knots."

Re: Could pilots with a commercial licencse have hit the the World Trade Center and the Pentagon with a 767 or 757 at the speeds observed on 9/11?
At low altitudes, drag and thermal effects are much more severe than they are at high altitudes, because of the higher air density at low altitudes. An airliner flying at 650 miles per hour (565 knots, added not by author) at sea level, or a fighter flying at MACH 2.5 at sea level, would probably be torn apart by the denser air. (In fact, at least two 737 accidents involved “frozen” rudder mechanisms which caused the jets to go into full-speed powered nosedives, and both 737s came apart before hitting the ground). So drag is much higher at lower altitudes, making it harder – and more dangerous – to fly at top speed through the denser air.
Not only that, but engines having all that dense air shoved into them (if they were flown very fast at low altitudes) would get dangerously hot. Remember how, when we talked about ramjets, we said that the turbine inlet temperature was just about the most important restriction that limits the thrust an engine can put out. The air at lower altitudes is hotter and at higher pressure than high-altitude air. If you compress that low-altitude air, it becomes even hotter. Engines have a much easier time working with high-altitude air: When the engine takes in air that is colder and less dense to begin with, it can be compressed more before reaching those limiting temperatures. This means that the colder and less-dense air at higher altitudes allows a jet engine to run at higher RPMs and at higher compression rations, which make it more efficient. It also means that the engine intake can swallow more of that air per second and compress it properly, and thus burn more fuel and generate more thrust.

I am ex-Air Force and a pilot with tons of hours in several types as well as professional 767 simulator time.

No matter how many times a hijacker practiced such a maneuver on a PC simulator, the G-forces of the last turn exhibited by the second tower aircraft would have made it next to impossible for a human.

That is a 500 knot, 90 degree bank at sea level, meaning the pilot was pulling the maximum possible Gs - which a 767 cockpit is not equipped to handle.

By this, I mean that the pilot would have been unable to move the controls when subjected to 7+ G because the seat is upright and the pilots arms must extend straight out to reach the yoke.

His arms would have fallen off the yoke, so it is a self-limiting exercise.

This is assuming that the 767 does not have a limiter and stick shaker set to prevent such violent maneuvers. I'd have to check the POH or even call some guys at Boeing I used to know.

The smoking gun is the perfect, vertical demolition of the towers AND BUILDING FUCKING SEVEN (!!!!).

The smoking gun of this farce doesn't have to be the aircraft.

You find one smoking gun and you have a farce.

Period.

Anyway, my point is that those plane were flown by computer - and NOT the standard autopilot. All that can do is hold altitude, speed and heading.

Of course, maybe those planes didn't even exists. Hmmm? Ever see a modern action movie?

 Quoting: George B


Look at the flaps on the jet's wings as it flies over the runway.

The flaps are extended to provide more lift, so the plane probably isn't going more than 200 -225 MPH or so. If it was, the overspeed condition would damage the flaps and make the plane uncontrollable.

Maybe one of our 757 experts could tell us what the maximum speeds are for the different flap settings.

I wonder if they were told they could fly thru it.

Question can ground effect be overcome at 500 mph..?

No. Thats why planes flying very fast never crash.

Ground effect applies to aircraft flying parallel to the ground. Not vertically into it.

According the officially approved story the plane that hit the Pentagon was flying at a very low altitude for at least half a mile before hitting the building.

Also, the POH of the 767 states to never exceed 250kt below 10k feet.
 Quoting: Anonymous Coward 34564994


POH? Do you have a link?coffee4
 Quoting: George B


Operating Performance: 200/300/200ER & 300ER
• Vno/Mno 360/0.80 Normal Operating Speed
• Vne/Mne 516/0.86 Mach Never Exceed Speed
• Vat 140-145 knots Landing @ Runway Threshold Speed @ MLW full flap/Gear down
• Vat with X-Plane is @ 50'.... 25'....10'
• Max Cruise 488 - 492 kts , Long Range Cruise 457 - 461 kts
• Max Alt. 43,000' , Long Range Alt 33,000' - 39,000'
* DO NOT Exceed 250kts @ or Below 10,000ft Altitude.*

[link to knology.net]

Cruise Speeds:
• Max Cruise Speed is 490kts @ 35,000'
• Long Range Cruise is 460 - 465kts @ 35,000 - 39,000'
• Cruise Speed 485 - 490 kts Cruise Altitude 30,000 - 39,000ft depending on weight.
• Typical Cruise Speed is 0.78 - 0.82 Mach @ FL300 - FL390 (30,000-39,000ft)


MLW = Maximum Landing Weight
MTO = Maximum Take-off Weight
V2 = Safe Climb-out speed (The speed after Vr, Rotation speed or Lift-off speed) Vat = Landing speed at runway threshold Flap/Gear down (X-Plane @ 50'...25'...10') Vapr= Approach Speed , just add 5-10kts to Vat with flap/gear down @ MLW or less Vno = Normal Operating Speed
Vmo = Maximum Operating Speed
Vne = Never Exceed Speed
FL350 = Flight Level 35,000'

Re: Could pilots with a commercial licencse have hit the the World Trade Center and the Pentagon with a 767 or 757 at the speeds observed on 9/11?
I am ex-Air Force and a pilot with tons of hours in several types as well as professional 767 simulator time.

No matter how many times a hijacker practiced such a maneuver on a PC simulator, the G-forces of the last turn exhibited by the second tower aircraft would have made it next to impossible for a human.

That is a 500 knot, 90 degree bank at sea level, meaning the pilot was pulling the maximum possible Gs - which a 767 cockpit is not equipped to handle.


By this, I mean that the pilot would have been unable to move the controls when subjected to 7+ G because the seat is upright and the pilots arms must extend straight out to reach the yoke.

His arms would have fallen off the yoke, so it is a self-limiting exercise.

This is assuming that the 767 does not have a limiter and stick shaker set to prevent such violent maneuvers. I'd have to check the POH or even call some guys at Boeing I used to know.

The smoking gun is the perfect, vertical demolition of the towers AND BUILDING FUCKING SEVEN (!!!!).

The smoking gun of this farce doesn't have to be the aircraft.

You find one smoking gun and you have a farce.

Period.



Anyway, my point is that those plane were flown by computer - and NOT the standard autopilot. All that can do is hold altitude, speed and heading.

Of course, maybe those planes didn't even exists. Hmmm? Ever see a modern action movie?
