I am going to dedicate this thread on analyzing many Airline crashes that slammed into the ground and showing how much of the plane is left to prove it crashed there. This will be an indepth comparison to the crashsite of flight 93. Pulkove Airlines flight 612 crashed near the Ukranian city of Donetsk killing all 170 people on board. As the Tupolev Tu-154 reached 39,400ft. it stalled, went into an uncontrollable spin and slammed into the ground at over 500mph. Unlike America's flight 93 on 9/11 which somehow does a disappearing act of any evidence of plane......well, let's let the pictures do the talking. Russian flight safety takes nosedive - Aviation- msnbc.com Tupolev Tu-154 - Wikipedia, the free encyclopedia Local residents react standing among the wreckage of the Tupolev Tu-154 at the crash site near the Ukrainian city of Donetsk, about 400 miles (640 kilometers) east of Kiev, in this Aug. 23, 2006, file photo. The crash that killed all 170 people on board. The following is a well documented statement from a former aircraft accident investigator who signed a petition for a new investigation into the events of 9/11.... Col.

Essay: "In all my years of direct and indirect participation, I never witnessed nor even heard of an aircraft loss, where the wreckage was accessible, that prevented investigators from finding enough hard evidence to positively identify the make, model, and specific registration number of the aircraft -- and in most cases the precise cause of the accident. ... The government alleges that four wide-body airliners crashed on the morning of September 11 2001, resulting in the deaths of more than 3,000 human beings, yet not one piece of hard aircraft evidence has been produced in an attempt to positively identify any of the four aircraft. On the contrary, it seems only that all potential evidence was deliberately kept hidden from public view. With all the evidence readily available at the Pentagon crash site, any unbiased rational investigator could only conclude that a Boeing 757 did not fly into the Pentagon as alleged. Similarly, with all the evidence available at the Pennsylvania crash site, it was most doubtful that a passenger airliner caused the obvious hole in the ground and certainly not the Boeing 757 as alleged. As painful and heartbreaking as was the loss of innocent lives and the lingering health problems of thousands more, a most troublesome and nightmarish probability remains that so many Americans appear to be involved in the most heinous conspiracy in our country's history."
