July 21st was Anniversary of Danny Jowenko's Death

Dutch controlled demolition expert  Danny Jowenko died in a car crash a year ago this past July 21st.  When first shown video of the collapse of WTC7 Jowenko immediately acknowledged it was a controlled demolition.  Only afterwards was he told that it was WTC7 and that it happened on 9/11.  He was shocked, but continued to maintain that it was indeed a controlled demolition.  I'm not sure, but I think he was first shown the video in 2006.  So was his death an accident?   I'll always wonder.
