I can not remember the platform I watched it on. It would be sad to say it wasn't on YouTube. But in this video, a flight attendant was talking about how she believes the people aboard the flights of 9/11 were taken to a hanger someplace and gassed. She talks about how the flight attendant on the call mentions a part of the plane that nobody could have been in unless the plane was landed and the door was open.
I can not find it anywhere. From what I can sort of remember, the title of it was something along the line of.... 9/11 What really happened or The truth about 9/11
But when I look these titles up, it doesnt show anything.
Much appreciated in advance to anyone that can help me find this video again.
You may be thinking of Rebekah Roth. She says the flights landed in Westover Massachusetts. The timeline works. She has put out some good insight into the events, with a few hiccups though. "Upstairs" might be the clue you are looking for as there were no stairs on any of the flights that day. Definitely worth hearing what she has to say.
