It could not have been the stored kinetic energy of the parts because the aircraft trajectory was to the south in a different direction...
Ummm...if you had watched the video you'd have seen that the parts of the engine that rotate are going to fly off perpindicular to the axis of the fuselage...that's 90 degrees from the heading of the airplane, at the time of engine part separation. SO, you just proved my point! Thanks, mate!

Who implies that the parts "bounced" along the ground, through trees??? Don't people realize that things will get thrown up into the air, and follow an arcing path as they fall back to the ground???

As Weedwacker said trremendous energy stored in aircraft at impact time
That energy has to be dissapated somehow .
Engine spins parts away two miles distance upon impact with earth? Of course. Only on 9-11 along with all the other physics anomalies.
Umm weedwhacker? Indian Lake is not 90 degrees from the heading of the aircraft. It is 45 degrees. So much for your new theory.

Since this is a discussion concerning UAL93, I'd like to bring something to the table to show why I feel there is very good reason to believe that UAL93 crashed as we were told.
No, the fact that part of one of the engines ended up a few hundred feet from the crater is just that, a fact. And that fact hasnt changed.

No, THIS is what I said...

And again, where did I mention the word "pond"? Nowhere.

Are you one of those people who if they aren't given a good enough reason about why would it have been planted that it must of landed in the pond even though there's really no hard evidence that it did?

Why bother? Do you feel the location of a part lends crediblity to a claim?
Seriously, what would be the point?

And once again, what will you accept as evidence? A news story? A statement from a police officer? A quote from a dreaded FBI agent? WHAT?

Absence of evidence is not evidence of absence.
What?!?! This isn't Rumsfield land! Absence of evidence in this case means Their aint no evidence just people claiming their is.
Uncontained failures are among the most dangerous types of jet engine malfunctions because material inside the engine can break off and penetrate the housing, also called the cowl or shroud, that contains the engine's internal components. The debris could then strike portions of the attachment holding the engine or other parts of a plane's wings, tail or fuselage.
It is just this type of in-flight failure than caused the crash of a United Airlines DC-10 during a landing at Sioux City, Iowa on July 19, 1989. In that event, a CF6 installed in the aircraft's tail experienced what former National Transportation Safety Board Chairman Jim Hall called "a catastrophic failure" while the plane was at 37,000 feet. During the emergency landing attempt, 111 people of the 296 aboard were killed.
"Fractured segments from the center engine's fan hub, blades and shrapnel perforated the aircraft's horizontal stabilizer and severed hydraulic lines to all three hydraulic systems," Hall said during a 1997 speech in Chattanooga, Tenn., delivered four years to the day before Monday's crash.
The NTSB investigation later revealed the failure of the CF6 started with a tiny, microscopic crack in the engine's hub that occurred years before the 1989 accident. NTSB documents also showed the engine had been inspected six times before the crash and never detected. The cause of the crack, which grew to one-half inch in length by the time of the Sioux City accident, was metal fatigue.
In its analysis of the 61 CF6 uncontained failures, the FAA review stated in one variant of the engine, the CF6-50, there have been 16 events "where the debris escaped the engine case, 12 where debris escaped both the case and the nacelle, and nine where the debris escaped the entire engine area and struck other parts of the aircraft."
The other engine variant, the CF6-80C2 had experienced 16 events where "the debris escaped the engine case, six where the debris escaped both the case and nacelle, and two where the debris struck the aircraft." Nacelles are the housing that holds both the engine and its exterior casing.
Other uncontained failures involving CF6 engines include:
-An Air France Boeing 747, which sustained an uncontained failure of a CF6 when the engine was fired up at Charles de Gaulle Airport on March 24, 1996. Fractured bolts found after the incident caused the failure.
-A United Airlines DC-10, which sustained an uncontained engine failure during its take-off roll from Chicago's O'Hare International Airport on May 1, 1995. According to an NTSB report, the flight crew heard a loud crack and successfully aborted the take-off. Later inspection revealed fractured bolts and other parts had broken off of the engine.
-A Continental Airlines DC-10 suffered a failure during takeoff from Narita International Airport in Tokyo in March 1995. NTSB's investigation revealed fragments of the CF6's turbine blades had broken off and penetrated the engine's housing.
