This audio recording above of Kevin Cosgrove’s final moments alive at the 105th floor of 2 WTC on 9/11 is probably the most frightening piece of audio I have ever listened to.

Up until now the most haunting report I’ve seen coming out of 9/11 is the video of people jumping from the towers, but man, this audio recording above is really on another level. The recording goes on for several minutes until the final moments of 2 WTC collapsing at which point you can hear Kevin Cosgrove scream and suddenly cut out.

According to Wikipedia, Cosgrove’s 911 call was used to prosecute Zacarias Moussaoui.
