This week on 9/11 Free Fall, civil engineers Seth McVey, Zaida Owre, and Roland Angle join host Andy Steele to talk about AE911Truth’s landmark initiative Project Due Diligence (PDD).

McVey and Owre, who are first-time guests on the show, and Angle, who is AE911Truth’s CEO and the founder of PDD, explain why they enthusiastically lend their time, energy, and expertise to this successful effort to share the WTC evidence with others in their profession.

They also discuss how AE911Truth supporters can advance PDD’s progress as it breaks through the wall of disinformation and censorship threatening to bury the evidence for the controlled demolition of all three WTC towers on September 11, 2001.
