Here's what I think.
1. There's no way the US govt doesn't know exactly where this plane went. Ditto for Israel, which continues to have a certain segment of it's military on constant watch due to this event.
2. The whole show in the S. Indian Ocean was a charade. A diversion.
I'm afraid this plane was landed in enemy territory and will be refurbed and put into some type of circulation but will ultimately be loaded with a nuke and sent into Israel or the US. This is the next big splash from a group fascinated with mass killing potential of airplanes. The enemy wants the next big thing to be unprecedented. And this would/will be.
