You disgusting little dishonest piece of shit.
No one proclaims the calls as "hard evidence" what they are evidence is the trauma, dignity, and spontaneous bravery of a few men, and women, who spent their last moments fighting and dying for their life.
Hundreds of people, including volunteers from their county fire and paramedic departments rushed to the crash site of United 93. These were the people who came across the plane and it's passengers wreckage.
You are incredibly ignorantly implying both the family members who took the calls, and these volunteers who were first to arrive are either lying, deceived or idiots.
You fucking wanker.
