One picture appears to be an orange life jacket.
All of the life jackets I’ve seen on airplanes are inflatable with connection straps at the bottom rather than ties in the middle, so much different from what the picture shows. Of course, I’ve only looked at life jackets on US carriers.
Could actually be a life jacket. Whether it is from the plane is much more doubtful. If the plane fell into the ocean from 36,000 feet, there is going to be a lot of debris floating around out there.
Give it a couple more days and I suspect they will find the debris field.
It’s confirmed...bodies seen in water as well as debrie identifying the plane.
