2-MSTG is not French. It's privately owned, registered to Oceanskies in the UK.
The FR AWACS is probably a normal flight. I was told there's a big NATO exercise over EU right now. AWACS do air traffic control over a theater of operations, among other things. Anyway it stopped indicating an emergency. Sometimes they will squawk emergency because it's a drill to test what happens when a plane has an emergency. I'm not concerned, just monitoring, because once in a while an emergency really is an emergency.
