WTC Twin Towers plane crashes
FEMA says the plane tore through the steel core
Plane’s nose cone made of carbon
The nosecone of a Boeing passenger plane, pictured below, is composed of carbon. Its function is to serve as an aerodynamic cover for the aircraft’s navigation system. It is not designed to be utilized as, and it will not perform well as, a missile warhead. Impact with the very first masonry wall would have completely obliterated the plane’s nosecone and enclosed electronics. The plane’s fuselage, composed primarily of strong yet lightweight metals, would have fared only slightly better.
Boeing has a plastic nose cone
Cruise missile has armor piercing steel and “depleted” radioactive uranium nose.
Boeing 757 has a plastic radome nose.
Boeing plane had composite nose cone
The nose cones (since they cover sensitive radar equipment) of most aircraft are made of composite materials. This is true of the 757-200. The aircraft on the left has been impacted by a bird. The idea that the nose of Flight 77 made a journey through the Pentagon and punched a hole 3 rings in and 310 feet away from the impact is hard to accept.

Thin aluminum-carbon skin vs steel columns
My comment: Compare the thicknesses of the columns that made the walls of the WTC Twin Towers and the thickness of the aluminium skin of the planes. Aluminium alloy is chosen as the metal skin for aircraft for its lightness. It has low tensile strength compared to other metals and so aircraft skin can be easily fractured and punctured on impact.
Aluminum skin of aircraft
Aluminum alloy (Alcoa, Inc.) is used for fuselage/wing frames and skins. The thin aluminum skin and fuselage frame, are the only protective barriers (excluding cabin paneling) between the crew, passengers and potential disaster. Aircraft aluminum alloy is efficacious because of its light weight and heat resistance. However, there are several major deficiencies:
1. Aircraft aluminum has a lower tensile strength: ultimate strength by a material at the moment of failure (81,000 psi) than Kevlar (485,000 psi). Aluminum also has a lower modulus of elasticity: material’s resistance to extension (10,600,000 psi) than Kevlar (14,000,000 psi).
2. Because of aluminum’s low tensile strength and modulus, the fuselage frame and skin have less impact, cut, tear and puncture resistance than Kevlar. When an aircraft crashes at high speed, fracture and disintegration of the aluminum fuselage frame and skin can occur immediately upon impact. These events increase the probability and extent of fire, smoke, toxic gases and explosion, usually resulting in a high incidence of fatalities.
Structure of the WTC Twin Towers
Look at the scale of the exterior columns compared to the man in the picture.
The WTC towers, also known as WTC 1 and WTC 2, were the primary components of the seven building World Trade Center complex. Each of the towers encompassed 110 stories above the Plaza level and seven levels below. WTC 1 (the north tower) had a roof height of 1,368 feet, briefly earning it the title of the world’s tallest building. WTC 2 (the south tower) was nearly as tall, with a roof height of 1,362 feet. WTC 1 also supported a 360-foot-tall television and radio transmission tower. Each building had a square floor plate, 207 feet 2 inches long on each side. Corners were chamfered 6 feet 11 inches. Nearly an acre of floor space was provided at each level. A rectangular service core with overall dimensions of approximately 87 feet by 137 feet, was present at the center of each building, housing 3 exit stairways, 99 elevators, and 16 escalators. (FEMA)
Both the central core and the outer wall supported the gravity load (were load bearing). The core provided the strength needed to support the bulk of the weight, while the outer wall provided the necessary rigidity to resist lateral loading due to the wind. The requirement to resist lateral loading, is the dominant feature determining the design of tall buildings. (Guardian)
Figure 2-3 presents a partial elevation of this exterior wall at typical building floors. Construction of the perimeter-wall frame made extensive use of modular shop prefabrication. In general, each exterior wall module consisted of three columns, three stories tall, interconnected by the spandrel plates, using all-welded construction.
At the building base, adjacent sets of three columns tapered to form a single massive column, in a fork-like formation, shown in Figure 2-4.
Figure 2-7 (left) shows the erection of prefabricated components, forming exterior wall and floor deck units.
Figure 2-8 (right) shows the erection of floor framing during original construction.
The buildings’ signature architectural design feature was the vertical fenestration, the predominant element of which was a series of closely spaced built-up box columns. At typical floors, a total of 59 of these perimeter columns were present along each of the flat faces of the building. These columns were built up by welding four plates together to form an approximately 14-inch square section, spaced at 3 feet 4 inches on center. Adjacent perimeter columns were interconnected at each floor level by deep spandrel plates, typically 52 inches in depth. In alternate stories, an additional column was present at the center of each of the chamfered building corners. The resulting configuration of closely spaced columns and deep spandrels created a perforated steel bearing-wall frame system that extended continuously around the building perimeter.
The core consisted of 5-inch concrete fill on metal deck supported by floor framing of rolled structural shapes, in turn supported by a combination of wide flange shape and box-section columns. Some of these columns were very large, with cross-sections measuring 14 inches wide by 36 inches deep
[Some columns were even larger. “Columns in lower core are almost solid steel and weigh up to 56 tons each.” Engineering News Record, January 1, 1970. ]
These rectangular box columns transitioned into heavy rolled wide flange shapes.
[..] [P]icture (below) of the transition from box column to H-column (heavy rolled wide flange shape). (Guardian)
Caption: The first is the classic helicopter photo of the top floor of a tower under construction.
Caption: Here is another image taken from the street level when the tower was but five or six floors tall.
This shows the plane entering the core but the plane is incorrectly shown in this picture. The plane should not be shown intact. The plane was blown up before it entered the tower. Even if it hadn’t been blown up the plane would have had to pass through the exterior wall of the tower. After it had gone through that the plane would not resemble the undamaged plane in the picture. The wings would not have been present. The nose and fuselage would have suffered considerable damage by this point. The plane would not be intact but broken up into pieces. This is moot anyway as photos show the plane to have disintegrated in a bomb blast OUTSIDE the tower, showering down confetti-like metal debris.
My comment: This picture shows metal columns and plane parts showering down like confetti. The force of the explosion expelled the columns laterally. If gravity acted alone, the various pieces of debris would have fallen straight down.
Holes in the wall – Pentagon
Newly renovated section was the section that was hit by the plane.
Debris is marked with green color – could this be missile debris in the foreground?
The wall looks about 2 feet thick, so the inner walls may have been constructed in the same way as the outside wall which is 2 feet thick. That means the total thickness the plane’s nose had to travel through was 24 feet (of brick, concrete and limestone). Even if the inner walls were only 1 feet thick, the plane’s nose would have had to travel through 7 feet thick barrier in total. Look at the comparison with the F-4 Phantom jet test where the jet slammed into a twelve-foot thick concrete barrier at 400 mph and the barrier remained intact.
“The purpose of the test was to determine the impact force, versus time, due to the impact, of a complete F-4 Phantom – including both engines – onto a massive, essentially rigid reinforced concrete target (3.66 meters thick). Previous tests used F-4 engines at similar speeds. The test was not intended to demonstrate the performance (survivability) of any particular type of concrete structure to aircraft impact. The impact occurred at the nominal velocity of 215 meters per second (about 480 mph). The mass of the jet fuel was simulated by water; the effects of fire following such a collision was not a part of the test. The test established that the major impact force was from the engines. The test was performed by Sandia National Laboratories under terms of a contract with the Muto Institute of Structural Mechanics, Inc., of Tokyo.” – Sandia Laboratories (1988)

For more information on viewing these launches check out the Space Archive web site. Brian does a bang up job at alerting people of these spectacular events.
My comment: You can see a missile vapor trail on the right of the picture as the plane flies low heading for the Pentagon. The vapor trail appears just to the top and right of the pillar on the right.
My comment: You can see the vapor trail which has thinned out now and the fireball produced by the detonation of the ordnance. Notice the white shade of the fireball. The white shade indicates very high temperatures.
Statement of Penny Elgas: witness to the Pentagon crash
“The plane seemed to be floating as if it were a paper glider and I watched in horror as it gently rocked and slowly glided straight into the Pentagon. At the point where the fuselage hit the wall, it seemed to simply melt into the building. I saw a smoke ring surround the fuselage as it made contact with the wall. It appeared as a smoke ring that encircled the fuselage at the point of contact and it seemed to be several feet thick. I later realized that it was probably the rubble of churning bits of the plane and concrete. The churning smoke ring started at the top of the fuselage and simultaneously wrapped down both the right and left sides of the fuselage to the underside, where the coiling rings crossed over each other and then coiled back up to the top. Then it started over again — only this next time, I also saw fire, glowing fire in the smoke ring. At that point, the wings disappeared into the Pentagon. And then I saw an explosion and watched the tail of the plane slip into the building. It was here that I closed my eyes for a moment and when I looked back, the entire area was awash in thick black smoke.”
Could she have been describing the smoke/vapor trails of a missile being fired from the underbelly of the plane?
“I saw a smoke ring surround the fuselage as it made contact with the wall. It appeared as a smoke ring that encircled the fuselage at the point of contact and it seemed to be several feet thick.

Were the “churning smoke rings” the rotating smoke trails of a torpedo fired into the Pentagon?
Did Penny Elgas’s churning smoke rings come from this?

Damage: WDU-17/B Warhead
The current Sidewinder, as well as its replacement, the AIM-9X, carries the 20-pound (9-kg) WDU-17/B warhead. The WDU-17/B consists of a case assembly, a good amount of PBXN-3 high explosive, booster plates, an initiator device and nearly 200 titanium fragmentation rods. When the target detector senses the enemy aircraft, it activates the fuze mechanism, which sends an explosive charge through the initiator (a train of low-explosive material) to the booster plates. The explosive charge from the initiator ignites low-explosive material in the booster plate channels, which ignites explosive pellets surrounding the high-explosive material. The pellets ignite the high explosive, causing it to release a huge amount of hot gas in a short amount of time.
The powerful explosive force from this expanding gas blasts the titanium rods outward, breaking them apart to form thousands of metal pieces, all zipping through the air at top speed. If the warhead goes off within range of the target, the speeding titanium fragments will break apart the enemy aircraft’s fuselage. In some cases, the missile may go right up the target’s tailpipe, demolishing the aircraft from the inside. The WDU-17/B is referred to as an annular blast fragmentation warhead because the explosive force carries the metal fragments outward in all directions, in an annular, or ring-shaped, pattern.
My comment: The fragmentation of the WDU-17/B warhead on detonation is in a ring-shaped or annular pattern. Penny Elgas describes the smoke rings from the plane that hit the Pentagon moving in a ring-like pattern.

Comment: In the video you can clearly see squibs shooting out in a ring around the South Tower split seconds before the missile part shoots out of the building after making a track through the tower and exploding. The ordnance fireball is visible in the video. It is not clear whether the squibs come from the missile detonating or from accompanying bombs that are detonating at the same time as the missile is firing.

Cruise missile information
Of the two most notable types of cruise missile, the Tomahawk, most often used by the Navy, is 18 feet, 3 inches (5.56 m) long and weighs 2,900 pounds (1,315 kg). The Air Force AGM-86B/C weighs 3,150 pounds (1,429 kg) and measures 20 feet, 9 inches (6.3 m).
A cruise missile includes a solid rocket booster, which makes up approximately fifteen percent of its weight at launch. Once it has burned its fuel, the booster falls away and the missile’s wings, tail fins, and air inlet unfold. From that point until it reaches its target, the missile is powered by its turbofan engine. In flight, the cruise missile has a speed of about 550 miles per hour (880 kph).
Guiding these missiles are four different systems: the inertial guidance system, which detects changes in the missile’s motion; terrain contour matching, which applies a three-dimensional database of the terrain over which the missile flies; global positioning system (GPS), which includes both military satellites and an onboard GPS receiver; and digital scene matching area correlation, which switches on once the missile nears its target, using an image correlator and a camera to locate the target.
Missile seeker technology
Sidewinder – how it works
The Sidewinder AIM-9 (air intercept missile 9) is classified as a short-range, air-to-air missile. Simply put, its job is to launch from an airborne aircraft and “kill” an enemy aircraft (damage it to the point that it goes down). Missiles like the Sidewinder are called smart weapons because they have built-in seeking systems that let them home in on a target.
In 1947, a Naval physicist named Bill McLean took it upon himself to build a better system — a missile that would seek out the heat from an enemy aircraft’s engine system. Since the missile would home in on the target’s own emitted energy, rather than reflected radio energy, the pilot could “fire and forget” — that is, he could launch the missile and get clear. In place of the bulky radar equipment, the missile would use a relatively small heat-sensing photovoltaic cell to “see” the target.
Dimensions of a typical cruise missile
Cruise missiles are 20 feet (6.25 meters) long and 21 inches (0.52 meters) in diameter. At launch, they include a 550-pound (250-kg) solid rocket booster and weigh 3,200 pounds (1450 kg).
The booster falls away once it has burned its fuel. The wings, tail fins and air inlet unfold, and the turbofan engine takes over.
This engine weighs just 145 pounds (65 kg) and produces 600 pounds of thrust burning RJ4 fuel. The fuel load is 800 to 1,000 pounds (about 450 kg) of fuel at launch, or approximately 150 gallons (600 liters). The missile has a cruising speed of 550 mph (880 kph).
A cruise missile is a guided missile which carries an explosive payload and uses a lifting wing and a propulsion system, usually a jet engine, to allow sustained flight; it is essentially a flying bomb. Cruise missiles are generally designed to carry a large conventional or nuclear warhead many hundreds of miles with high accuracy. Modern cruise missiles can travel at supersonic or high subsonic speeds, are self-navigating, and fly on a non-ballistic very low altitude trajectory in order to avoid radar detection.
The AIM-9 Sidewinder is a heat-seeking, short-range, air-to-air missile carried by fighter aircraft and recently, certain gunship helicopters. It is named after the Sidewinder snake, which detects its prey via body heat and also because of the peculiar snake-like path of flight the early versions had when launched.
