All I am raising is questions. Too many questions in fact. Why, why, why.
There is no reason why we shouldn't be told the truth on the subjects. What are they protecting, or hiding from us.
If a plane fly's 2000 miles an hour, and can fly the whole United States in 1.5 hours at that speed. They can catch some jet liners going 500 mph. I'm sure the US military has ones that fly faster than that.
I don't trust Uncle Samuel, at all. |

Underlying the evolutionary theory is not just the classic "stuff" of science — conclusions arrived at through prolonged observation and experimentation. Evolution is first an atheistic, materialistic world view. In other words, the primary reason for its acceptance has little to do with the evidence for or against it. Evolution is accepted because men are atheists by faith and thus interpret the evidence to cor-respond to their naturalistic philosophy.

Dave,
I'm repeating questions, not lies per say.
Ever heard of Cause, Reaction, Solution. This is what happened here, It was used for the benefit of those that run the show, whether it was planned or a seizure of the moment, nothing else would have gotten us into Iraq. Sort of that.
Who stands to profit? The saying of old. Haliburton, oil, monopolies, you name it. They are no longer in control of the profits of their resources. |

Unfortunately, since the Latin phrase "per se" means "with respect to its inherent nature," then you're either asking questions for the sake of asking questions, or you're asking questions which are inherently based upon lies that other people have promoted as truth.
Either way, your questions stand in contradiction to your desire to see that people know the truth about what happened on 9/11/2001, regardless of who stood to profit. I'd like people to know the truth, also, and as far as I'm concerned, your questions do not further that cause, but instead make it look like the cause is being championed by idiots. |

It takes time to load weapons, fuel and take off. Also, supersonic flight uses fuel at an astonishing rate - I doubt if a fighter aircraft can fly across the US at that speed without refueling. Shooting down an airliner full of people is not an easy decision - no one would have considered doing this until after the first plane hit the WTC. Common sense is the first thing jettisoned in a conspiracy theory. |

Horse patooties. The release of CVR recordings is prohibited by law. Here's what the NTSB has to say about it:
quote: The CVR recordings are treated differently than the other factual information obtained in an accident investigation. Due to the highly sensitive nature of the verbal communications inside the cockpit, Congress has required that the Safety Board not release any part of a CVR audio recording. Because of this sensitivity, a high degree of security is provided for the CVR audio and its transcript. The content and timing of release of the written transcript are strictly regulated: under federal law, transcripts of pertinent portions of cockpit voice recordings are released at a Safety Board public hearing on the accident or, if no hearing is held, when a majority of the factual reports are made public.
http://www.ntsb.gov/aviation/cvr_fdr.htm
And here's the law itself, 49 U.S.C. § 1114
quote: (c) Cockpit Recordings and Transcripts.— (1) The Board may not disclose publicly any part of a cockpit voice or video recorder recording or transcript of oral communications by and between flight crew members and ground stations related to an accident or incident investigated by the Board. However, the Board shall make public any part of a transcript or any written depiction of visual information the Board decides is relevant to the accident or incident— (A) if the Board holds a public hearing on the accident or incident, at the time of the hearing; or (B) if the Board does not hold a public hearing, at the time a majority of the other factual reports on the accident or incident are placed in the public docket. (2) This subsection does not prevent the Board from referring at any time to cockpit voice or video recorder information in making safety recommendations.

Where on Earth did you get the idea that "we have been allowed to listen to them"? Can you cite even one pre-9/11 example?
This law has been on the books since 1975. http://www.law.cornell.edu/uscode/search/display.html?terms=1114&url=/uscode/html/uscode49/usc_sec_49_00001114----000-notes.html
Was it passed, 26 years before 9/11, as part of the Great Big Eevil Gummint Conspiracy?
It took me only about five minutes of Googling to find that out. Honestly, verlch, do you ever even consider doing the most rudimentary checking, like seeing what pops up with an ordinary search engine, before spouting a claim?

Nice unsubstantiated, conveniently vague tale of an ATV ride through the rubble with "a million dollars worth of equipment". One has to wonder just what that million dollars worth of equipment was intended to detect. There is an underwater locating device attached to CVRs and FDRs (if you look at this picture of a CVR the ULD is the gold-colored cylindrical thing mounted on one end of the box); what activates them is immersion in water. They're designed to transmit ultrasonic (37.5 kHz) pulses through water. The specific acoustic impedance of water is over 3600 times that of air (approximately 1,500,000 Rayles versus 410 Rayles for air). A transducer designed for efficient coupling to water will perform very poorly in air.
If I assume that the transducer's acoustic impedance is matched to that of the intended transmission medium of water (the condition for maximum power transfer) and start with the specification for acoustic output after 30 days (because these events are claimed to have taken place in October 2001) of 700 dynes/cm^2 (70 Pa) (see this spec sheet) and do the sums to account for the transmission loss due to impedance mismatch and to convert the resulting pressure to the dB SPL scale used in air acoustics, I get an expected SPL of approximately 65.5 dB @ 1 meter. Just perfect for penetrating ferroconcrete rubble and being located in a noisy environment like the Ground Zero cleanup.
I also can't help but notice that nowhere in this tale of hunting around for what would be a very weak signal from a device which one can't reasonably expect to have been activated at all is there any account of where the CVRs and FDRs were supposedly found, how they were extricated from the rubble or when this happened, save for the claim that it was in October. That's strangely indistinct for someone who was present at such an important find, but it's just right if you want to avoid naming a time and location lest someone who was actually there might contradict your claim.
The whole thing bears the hallmarks of a technically-illiterate attention-seeker making shit up and putting it over on an equally ignorant reporter. In other words, it gives off a very strong aroma of equine exhaust.

Damn. Especially when they point out things that one should know. Sir, I stand corrected. Shit, I obviously need to revisit my old math schoolbooks from high-school and college.
When you revisit them, look up angular acceleration, which is a bit more complex. I recall a demonstration in high school involving a meter-long piece of wood attached by a hinge to a base. The arm had a wooden cup glued to the top surface about 15cm from the end. The arm was raised to a a 30 degree angle and a marble was placed in a recess drilled into the upper end. When the teacher released his hold, the arm fell, smacking into the base, then, after a noticable pause, we heard the sound of the marble landing in the cup. The hinged arm "fell" faster than the marble did under the same gravitational acceleration, beating the marble to the ground by at least the height of the cup. We then did the math to calculate the velocity of the tip of the arm just before striking compared to the velocity of the marble.
Since that was 32 years ago, the calculations are far from the tip of my fingers, but I think it's safe to say that the forces acting on a collapsing building are far more complex than those acting on an apple falling from a tree.

I can't quite picture this, could you please explain it a little more fully?
I'm thinking of a cup on the ruler, "dropping" from 30 degrees from vertical back to the vertical. The marble drops from the top of the rule, the full 1m or thereabouts. The "Cup" only "falls" from 1/2 a meter vertically. It takes about 320 milli Seconds to fall 0.5 meters from rest, 452 milli Seconds from 1 meter.
There's a little more to it than that, as you've suggested, but I want to make sure I've got the right idea before I get carried away! |

My late night post was not clear. Base is horizontal and hinged arm is raised 30 deg from horizontal. Cup is glued to arm 10cm from free end and marble rests in depression in free end. The tip of the arm falls faster than the marble because of angular acceleration versus the marble's linear acceleration.
Even better than a description is the strobe picture.

Just to add a little to this. I believe the fighters scrambled that day were F16s. Now it takes several minutes to get one in the air unless its powered up on standby. IIRC it takes 8 minutes to fully align the navigation systems but a cut down start up can reduce this to 3. This eats into any catch up time. Once in the air the plane has a top speed of 1321 mph at altitude.
Flying at such a speed requires a lack of drop tanks in order to reduce drag. Also any weapons carried would slow this speed for the same reasons. Maintaining this speed will require full afterburner. At this throttle setting the F16 can use up in excess of 70,000 lbs of fuel per hour. The F16 in clean configuration only carries about 7000 lbs of fuel (enough for 6 minutes of flight before fuel starvation at full throttle)
If we allow drop tanks in all positions on the plane that ups the fuel to 14,000lbs, enough for 12 minutes flight. Its clear why you dont fly a plane like this even in most intercept situations. You likely wont reach the target (your range is 132/ 264 miles for the 7000lbs/14,000lbs fuel loads if you have no wish to return home or 66/ 132 miles if you want to land back at base) and when you do you have no weapons to fire as you had to leave them at home in order to race to the target. |

Excellent, that clears it up nicely. Thanks tw101356.
I've not seen that particular demonstration before, it's a good one. For those that are interested, I've created the following diagram:
It's important to remember that the rotational acceleration of the arm changes with time. The force due to gravity is constant, and always downwards, as shown by the green arrows in the diagram. To analyze the effects of the applied force, it makes sense to break it down into components in directions that will be more useful for calculation.
The force along the axis of the beam is not going to result in any change of motion, as long as we ignore friction in the hinge itself. These forces are shown in purple. The force perpendicular to the beam, along the tangent to the circle described by the beam, will be the force that is responsible for acceleration of the beam. This force is shown in red. The percentages are the magnitude of this force in relation to the force due to gravity. As you can see, this force starts out small (around 25% of the gravitational force, at 20 degrees, a number I picked arbitrarily, and will be a maximum at horizontal).
As anyone who has ever balanced a pencil/broomstick/rule on their finger knows, if you can get it stable and completely vertical, there is no tendency to rotate. In reality, you can never balance it perfectly by staying completely still, so it does tend to "fall" over eventually, but if you keep it near vertical, this acceleration is small, and easily countered with small corrections.
Also worth noting is that the cup that catches that marble in fact starts below the marble, so the title "Falling faster than gravity" is a little misleading.
An impressive demonstration I have helped set up uses a similar arrangement, but with an arm that can swing past the horizontal. The cup is designed to catch the falling marble exactly as it passes through the lowest point of the swing, horizontally. The purpose of the exercise was to see who could calculate the correct starting position for the (in our case, wooden) marble the most accurately. It resulted in quite a bit of chaos, and wooden spheres being whacked all over the place. Fun stuff, if you're into that sort of thing.
Edited to improve(I hope) clarity. |
