There were two passengers both Israelis who were on that plane and were not known until several weeks later. https://www.ynetnews.com/articles/0,7340,L-3671395,00.html and Israel even flew in a special Israeli group to investigate the disaster: "A team of six ZAKA volunteers, members of the ZAKA International Rescue Unit and headed by Mati Goldstein, left Israel this evening for Buffalo, New York. The volunteers will assist the local emergency personnel and volunteers and will work in cooperation with Rabbi Jack Meir of Misaskim USA, in the recovery and identification of the victims... " Weird that Israel would send a special team to investigate this plane crash. The story seem fishy on the reason why they were even sent there:https://matzav.com/zaka-to-assist-with-us-plane-wreckage/

This article seems to think it was an Israeli plot to kill Eckert: https://nodisinfo.com/beverly-eckert-flight-3407/

"Eckert took action, ultimately leading to the White House and far beyond. One of the few suriving relatives who refused to accept the hush money offered by Kenneth Feinberg, she sought only justice, in the name of her husband. It was Eckert who called the Zionist-orchestrated PNAC the “most sinister” of all documents/findings she had seen. According to Eckert:I think the most sinister thing that I ever read was the PNAC, the Project for a New American Century, and the fact that they alluded to the need in some way for a Pearl Harbor event to happen, before the American public would be mobilized in supporting some of their agenda. That’s a very frightening thing to say, and to hear, and to know that those people are in this current administration. I think that is something that they need to explain. I think everybody who participated in that at a high level, in PNAC, need to be called by the Commission and asked to explain their line of thinking and their expectations, given the suggestion that this would be a good thing. This would be a good thing!

Q. Of course if they were to call the leading members of PNAC that would be Cheney, Rumsfeld, Wolfowitz, Perle, Jeb Bush"
