Video Of A Plane Hitting Light Poles Options

The F-4 shows total vaporization of the airframe and also shows a flash at one point.

It would require more testing to determine what a Boeing would do at its possible speed at sea level when hitting a concrete, brick and otherwise reinforced building.

If we consider that the planes went right through 14" square steel tubular columns with at least 1/2" wall thickness and tons of loading from above at the trade towers, we can't think that light poles would do very much. To me, it is surprising that the planes took out so many of the perimeter columns at the towers. They no doubt could have taken out a lot of the floor trusses as well.

I don't think they could have deposited nano thermate however, or melted steel, nor caused free-fall disintegration of the towers.

Its hard to visualize without real testing what would happen between the wings and light poles.

I know that lead and copper bullets will penetrate steel easily at rifle velocities, but I figured it was a matter of the density of the lead and the short time at impact, which didn't give the lead enough time to splatter, and its density is greater than steels. Rather odd actually how velocity changes characteristics of metals. Shooting the same bullets at pistol velocities only produces splatters of the lead and copper.

A .223 will easily penetrate 1/4" of steel plate as will a 30-30. A 30.06 will penetrate up to 1/2" or more of steel plate if shot squarely. All with copper jacketed lead bullets.

Airliners fly at best about the speed of a .45 bullet from a pistol. Less than that at sea level.

I think we could see a great amount of disintegration of the plane against the Pentagon, with parts going through weaker points in the walls.
Without knowing how thw walls were reinforced, its hard to determine even subjecvtively, the mass of the walls versus the mass of the plane.

Still, I don't see how there would be round holes in six walls through the three rings of the Pentagon, especially with all the 2' square pillars inside. It doesn't make sense, you can't have total disintegration and total penetration at the same time.

To me, its peculiar that the planes that hit the towers, went right in, yet at the Pentagon, the plane vanished outside. And after watching all the Pilots for Truth DVDs, it looks more like nothing hit the Pentagon, or maybe a misslie combined with wall penetration charges.

I think its wise to look into any evidence that the light poles weren't there that morning. If somehow it proves that they were, then the mystery about eyewitnesses, black box recorders and all that has to be weighed again.

Another thing, is someone seeing a plane flyover from the other side of the Pentagon.

If someone faked the parking gate five frames and faked the black box recorder, then what we have is the damage, and the eyewitnesses, combined with the motive to fake those things. Then we have the light poles.
Its hard to discredit the eyewitnesses.
The scene at the Pentagon front is really non-conclusive.
The holes through the Pentagon are very odd.
The light poles are the key and are quite tricky.
Its between the light poles and the eyewitnesses. They tell two different stories.

Here is a relevant study i came across on some forum a long time ago and saved copy/paste. Feel free to check the numbers...

Get ready for school.

The boiling point of aluminum is 4566 °F . This is the point at which it goes from liquid to gas.
Most of the aircraft consists of this. There are about 47 tons of it in this air frame.
The boiling point of iron - the primary component of steel is 5182 °F.
The engines and gear are made up of this.
There is about 13 tons of this in this air frame.

The maximum you can get JP-8 fuel to is 1796 degrees Fahrenheit.
4566 - 1796 =
2770F that need to be created by impact to vaporize the bulk of aluminum.

I know it has been a long time since chemistry class but you need this.

The heat required for vaporization is 294,000J per mol of aluminum.

Since 39% of this heat could be made up by the burning jet fuel. If it competly covered the aircraft and it was at max temperature. Which would require 5 times the aircraft's amount of maximum fuel to be aboard, but this I will overlook.

That only leaves about 177,000J of energy that needs to be made up by force of impact. Per Mol of aluminum.

There are 26.9815386 grams in a mol of aluminum.
So how much energy, in this case heat, does 27 grams make when it hits an object at 550mph? An immovable object for sake of equation.
Standard energy equation.
Energy = 1/2 mass *velocity (sq)
When your parents tell you that speed kills in vehicle accidents THIS is why.
.026 kilograms * 887 kph (550 miles per hour) squared = energy
.026kg * 786854 = 20,458 Joules created by impact at 550 mph
Which is not enough to vaporize any of the aluminum or any of the steel. Titanium is even higher on the scale.

So just like Mythbusters I will find how fast it would need to be going to vaporize on contact with an immovable surface.
177,000 Joules is required on top of jet fuel heat.
177,000 /20,000 = 8.85 times faster than that
So 550mph * 8.85 = 4867.5 mph which is roughly Mach 7 would do it.
This is if the jet fuel was applied evenly over the entire airframe and if the entire airframe came to the surface at the same time. If the nose hits first it slows down the fuselage some and reduces the energy that will be needed for the tail of the aircraft.
This is why all aircraft disasters produce wreckage.
