“.......because the guy across from Fuddy (Yamamoto?) had a reddish-maroon shirt on. ....”
In the video capture of the passengers in the cabin, isn’t the person with the reddish shirt sitting across from the sleeveless shirt person and not Mrs F?
I couldn’t tell what color shirt the person across from Mrs. F. was wearing.
It’s hard to try to align the people, so you have to go by by who is in front of each other on the right row of seats. Jacob Key is directly in front of Puentes, and the guy with the reddish-maroon shirt is directly in front of him. So the reddish-maroon shirt must have been across the aisle from Fuddy. There’s one screen capture I was able to get which shows just a little of the guy in the front seat on the right side, across from MW1, and he seems to have gray hair, which would make it Holstein - which fits his description of trying to get a different door open and not being able to.
The placement of the door is a mystery to me, because Puentes didn’t film people going past or around him, and yet it seems like the door at the back would have required it. The door hatch that was opened had a window on it so it could have been by Jacob Key’s seat, but then how was there a walkway for them to get out? The seat would have been in the way. Unless the seat folds up? I don’t know. It doesn’t make sense to me. The escape sequence is muddy, and I wonder if a lot of what happened there was edited out, to hide who all was in the plane.
