I have these questions.
These are programed to return to base if they lose connection. How was this changed?
These are not able to be tracked by radar. How was it found?
This is not damaged. who and how did they land it?
I can not tell you how big a deal this is on so many levels. The communication encryption in these is priceless. If someone has cracked that it is going to be a very expensive retrofit on many levels.
I have to believe someone in the ISI,Egypt or the White House has provided the Russians with this info.
My analysis is that as they said, or i think i read they said, it ran out of fuel loitering over a selected area. Out of fuel it can still fly by gliding to a landing. That can be controlled or uncontrolled, we don’t know which.
If the radio link were lost it could continue to fly till ran out of gas. It could then glide down to a belly landing and not actually “crash”
bottom line though, we don’t know and likely will never know what really happened
