Yep.

Good pics!

Here is the first appearance of "the hand". Leg with white tennis shoes is Jake. Both his seat and Hollstein's seat are shown in the video to be empty. No "manikin" in either. The hand appears to be attached to the two legs wearing dark colored pants.

Another image slightly brightened up to better show the shoe and pant leg of the person (Yamamoto) with "the hand".

Hollstein and Jake moved to the left to open the door. Jake is not carrying anything as he exits the plane. The 'manikin' if it existed would still be in the plane.

Jake at the door of the plane. No manikin in his right hand. Left I would guess is holding the rope handrail to the steps.
