This guy appears to have a ponytail, and if the dark mark on his cheek is glasses, it is a wider bow, not the narrow wire bows that Yamamoto has.
Certainly it's far from certain that the man in the image has a ponytail. And it's conceivable that Yamamoto could have been wearing eyeglasses with frames different than the eyeglasses he was wearing in his file photo from a couple of years ago. But that file photo tells us that Yamamoto has some visual impairment mitigated by eyeglasses; so does the man in the picture, or else he wouldn't be wearing glasses in the emergency.
The photo by the ambulance, where the rescue workers are patting somebody on the back (which seems like it would be the “distraught” Yamamoto who would need the extra comforting pat on the back) shows him wearing blue swim trunks (as he was later described at the Honolulu airport) and a sweatshirt, which he was probably wearing over the top of the shirt he was seen leaving the Honolulu airport in at about 7pm.
Haven't seen that photo. But if you say Yamamoto was wearing a sweatshirt and swim trunks at 7 p.m. that day, it certainly doesn't rule out the possibility that he had been given the sweatshirt to wear over the gray (?) shirt he may have been wearing earlier in the day in the image at # 45.
That guy could be Jacob Key.
No way! Key is Caucasian and has sandy brown hair. (Saw him on a video standing next to his wife, Rosa, who is the heavy-set woman of Asian heritage who was wearing the white shirt with the gray stripes in the water. Rosa was being interviewed about the incident.)
The guy we're talking about in the image is of Asian background and he's NOT the pilot Kawasaki. And he's not over 70 years old, or at least doesn't appear to be. By a process of elimination - assuming that the passenger and pilot identifications are correct - Keith Yamamoto is most likely the man in the image, second person from the right. (The first person from the right is surely Rosa Key.)
I think it's the same man, he's not wearing glasses, it's a shadow, and the watch looks the same to me, his hair is pulled back in a pony tail and it's visible on his neck, it looks like a collar, but it isn't. He's blowing up a vest, and his wife is the polynesian woman in the striped T shirt, closest to the camera.
All open to criticism of course.
I can’t see video, but the photo of Rosa and Jacob Key at http://www.kitv.com/news/hawaii/exclusive-2-survivors-in-molokai-plane-crash-speak-out/-/8905354/23461364/-/di8tpyz/-/index.html look to me as if Jacob’s skin is at least as dark as Rosa’s. Can’t see much of his hair but it doesn’t appear to be blond.
So who do you say is holding Fuddy’s hand by the door of the plane, if Yamamoto is over by Rosa Key?
