You’ll see that later on in the same thread, I searched for shoes that might have the same sole configuration seen in the water, and I posted an image of just such an item. Later, it was shown she was wearing black shoes with a thick, lighter coloured sole in an image from the aircraft interior. The colour yellow/green must have been due to the film itself, it changes from lime green through to yellow and then grey. So yes, it seems that is her shoe one sees.
Information under discussion PROGRESSES throughout the thread.
Yeah, sorry I did see that, I was just rereading some of the posts I missed over the weekend and I hadn’t seen your later posts when I replied.
