Hello Nelson111. After reviewing 777 evacuation slides on google I am even more convinced that what we are looking at in the photo is an evacuation slide from the 777. I know the advertised dimensions are off but the relative dimensions from the photo shows it to be a slide.
Might just be an evac slide, which means jet may have landed somewhat intact.
OR....
Its been air dropped there a long time ago to perpetuate the misdirection.
And what if.....it is real, and possibly, just possibly survivors?
Well the slide would float and it does appear to be something U-shaped.
Would that mean that the plane landed in the ocean and someone deployed the slide or could it deploy itself if it crashed???
