It's part two of a multi-part conference that happened a few years ago. Part one (and the first five minutes of part two) is just the intro. From then onwards, it's various air traffic controllers, pilots, retired colonels, majors, you name it, all testifying before a bank of TV cameras and journos - and all saying they will testify before Congress, under oath, if asked.
Mind-blowing stuff. Best evidence ever.
