Dutch demolition expert Danny Jowenko was killed in a car accident in the Netherlands in August 2011. He was reportedly driving from church when he collided head-on with a tree. There was also a dog in the car who survived. Jowenko is best known in the 9/11 truth community for his analysis of Building WTC7, which he concluded was a professionally-engineered controlled demolition. The reason he was killed is that many respectable people were convinced by him and were using his expert testimony.
This is a 2011 interview of Alan Sabrosky regarding 9/11.
“What we need to stand up and say is not only did they attack the USS Liberty, they did 9/11. They did it. I have had long conversations over the past two weeks with contacts at the Army War College, at its headquarters, Marine Corps and I made it absolutely clear in both cases that it is 100% certain that 9/11 was a Mossad operation. Period.” – Dr. Alan Sabrosky, March 14, 2010
