A little bit ago I posted the shoes that people were wearing. Fuddy’s were all black. The only ones who could have been wearing yellow shoes are Yamamoto and Puentes (the videographer). I’d have to check to be sure, but I believe the image of a person in the cage that was used by rescuers to lift the victims from the water is actually of Yamamoto, and I believe he is barefoot with dark shorts and dark gray shirt - which I believe also matches the image of the person being consoled by the back of the ambulance. Reports are that Yamamoto was seen later that evening in dark blue swimming trunks.
Keep in mind that aviation life vests or personal flotation devices may come in a black, yellow, and/or orange fire retardent 4 mil poly bag. So, some of the object or objects capturing your attention may be in part these bags or other paraphenalia from the aircraft and the survival gear.
