Israeli Art Students 9/11 Smoking Gun 

In the period leading up to 9/11, a group of Israelis managed to secure “temporary construction” passes to perform work on the 91st floor of Larry “pull it” Silverstein’s leased WTC 1. These passes gave them access to the entire WTC complex. The pretense was an art project called the “B-Thing” and the group is called Gelatin.
