Orion, I tried to watch the utube link, my connection is extra slow right now, I'll look later.
I believe I can guess as to the gist, though. But, I'm assuming for now.
It should be noted, firstly, that the area of impact just happened to be a 'reclaimed' strip mine. This means, the area consisted of very loose
You and I or a deer could walk across it, of course. But, an extremely high energy impact force entails a LOT of kinetic energy!! The Flight
Recorders are mounted near the tail of the airplane. They had mass, and energy, because of the speed the airplane was travelling at impact. They,
along with everything else on the airplane, were along for the ride. It is a chaotoic event, everything is not possible to calculate without a
Super-Computer, and just programming one, if you even had access, would be a daunting task.
Ya know, we prolly wouldn't even be debating this if the impact point terrain had been composed of different material. Say, a large asphalt parking
lot! But, it is what it is.
Consider the crash of that ValuJet into the Florida Everglades some years ago. OF course the Everglades are soft, everyone knows that. AND the
airplane was swallowed up...even at less than half the speed of the UAL93
Consider an horrific low-speed crash, such as NorthWest Airlines in Detroit. (I think flight 252...canlook it up). Airplane never exceeded about
160-180kts, yet due to its uncontrollability it dragged a wing, and broke up, spreading debris along a trajectory swath. YET, one, and only ONE
person survived...a four-year-old girl. She was seriously injured, but recovered. THIS is a prime example of how chaotic these impact forces can be.
Consider USAir flight 427, outside Pittsburgh, PA, in 1994. Straight in from about 3,000 above the ground. Starting airspeed was around 160kts,
accelerated to just under 290-300 at impact (still well less than UAL93) and photos of the crash site show large pieces, but a substantial amount of
wreckage buried itself....again, harder graound than Shanksville, and slower impact velocity.
(The exact numbers above, such as airspeeds, are from memory. I can, and will check-- plus invite anyone to research and further refine the data. My
point is, laws of motion, per Sir Isaac Newton, are irrefutable. At least we can agree on THAT. hmmmm?)
My attempted point is that every accident/crash sequence scenario will be different...there are many, many variables that affect the results.
One final example: Swiss Air 111, high speed (unknown) impact into the Atlantic Ocean off the coast of New Foundland. The pieces were shredded, and
we know this because they were recovered from the sea floor, at a depth of about 120 feet. Folks, this poor airplane hit WATER! And most pieces were
the size of a dinner placemat!
