THE PENTAGON BUILDING PERFORMANCE REPORT January 2003 6.1 IMPACT DAMAGE The height of the damage to the facade of the building was much less than the height of the aircraft’s tail. At approximately 45 ft, the tail height was nearly as tall as the first four floors of the building. Obvious visible damage extended only over the lowest two floors, to approximately 25 ft above grade. No photos of tail section outside or inside of building Where did the tail section go?
is that wheels up or down? Source this claim, please. Eta: the height of the tail (44' 6") is measured with the wheels down. As I recall from witness testimony, the wheels were up when AA77 impacted the Pentagon. The tail is not made of indestructible material is it?
what's amazing is that there was anything recognizable at all after slamming into a 24 inch re-enforced wall at high speed,much less having an intact tail section...
Being that two civilian airliners hit the WTC towers why is it so implausible that another one hit the pentagon?
You have probably seen the many photos of commercial jet crash sites. All with varying impact speeds and angles, with the majority of these sites having recognizable parts strewn across the impact area. I have yet to find any photos of Pentagon impact site showing recognizable wreckage
Of course they do...none of them flew into a 24 inch re enforced masonary and limestone wall either.... And the fact there wasn't anything recognizable was my point
I've highlighted the critical part you missed. In unusually violent crashes, it is NOT unusual for there to be no recognizable parts left around. PA 1771 is a good example. So is the flight that crashed in Iran. High speed crashes directly into the ground or another object generally don't leave big pieces around. The lower the speed of the crash, the more recognizable pieces are left. A pilot is usually trying everything they can to land safely which includes reducing speed. On 9/11, flight 77 was at full throttle and accelerating as it hit the Pentagon.
OK deduct 9 foot from the 44' 6", that still leaves 35' 6" foot of tail. Impact marks only extend to 25 foot
Lesson 25 ADDING AND SUBTRACTING FRACTIONS AND MIXED NUMBERS In this Lesson, we will answer the following: How do we add or subtract fractions? How do we add fractions with different denominators? What number should we choose as the common denominator? How do we add mixed numbers? Section 2 Subtracting mixed numbers. To add or subtract anything, the units -- the names of what we are counting -- must be the same. 2 apples + 3 apples = 5 apples. We cannot add 2 apples plus 3 oranges -- at least not until we call them "pieces of fruit" In the name of a fraction -- "4 tenths," for example -- the unit is the denominator, tenths. (Lesson 21.) 4 tenths + 5 tenths = 9 tenths. 1. How do we add or subtract fractions? 4/10 + 5/10 = 9/10 The names of what we are adding or subtracting -- the denominators -- must be the same. Add or subtract only the numerators, and keep that same denominator. Example 1. 5 8 + 2 8 = 7 8 . "5 eighths + 2 eighths = 7 eighths." The denominator of a fraction has but one function, which is to name what we are counting. In this example, we are counting eighths. Example 2. 5 8 − 2 8 = 3 8 . Fractions with different denominators To add or subtract fractions, the denominators must be the same. Before continuing, therefore, the student should know how to convert to an equivalent fraction. See Lesson 22, Examples 1, 2, 3, and especially Example 4. 2. How do we add fractions with different denominators? 2 3 + 1 4 Convert each fraction to an equivalent fraction with the same denominator. 3. What number should we choose as the common denominator? Choose a common multiple of the original denominators. Choose their lowest common multiple. (Lesson 23.) We choose a common multiple of the denominators, because we change a denominator by multiplying it Lesson 22. Example 3. 2 3 + 1 4 . Solution. The lowest common multiple of 3 and 4 is their product, 12. (See Lesson 22, Question 4.) We will convert each fraction to an equivalent fraction with denominator 12. 2 3 + 1 4 = 8 12 + 3 12 = 11 12 . We converted 2 3 to 8 12 by saying, "3 goes into 12 four times. Four times 2 is 8." http://www.themathpage.com/arith/add-fractions-subtract-fractions-1.htm that should help
You must have missed the part in Post #11 that Hannibal bolded. You may want to go back and read it again with the following in mind. http://www.helium.com/items/1352878-using-text-features-to-aid-comprehension That should help.
Excellent! You've answered your own query: according to the report, the fuselage tail sheared off at the slab above the second floor. No damage was seen above this mark. Lots of great info and evidence for AA77's impact into the Pentagon. I encourage everyone who has questions to study this report. Link
geee golly uncle bill, did it ever occur to you that is only the shear point which is not the same as tail height? More square dancing with hats! LOL

You asked for pictures of aircraft debris at the Pentagon on 911 and I gave them to you. Your welcome.
