You think we didn’t know about this moments after it happened, AWACS and E-2C probably picked this up during their regular surveillance missions over the Gulf or in Saudi airspace.
“somebody did something... like pushed the wrong button.”
Guaranteed, we knew nearly every detail of the missile launch immediately.
The problem is once launching, there would be no stopping the SA-15 TOR (if this was the system identified), from taking down a large commercial aircraft, in this case still accelerating just past 310mph and having climbed to about 10,000ft.
One also has to ask, why in the world was TOR (Gauntlet) active nearly adjacent to a commercial airport, and why would an air air defense command not be aware of commercial flights from a commercial airport. Or conversely, why was a commercial plane allowed to take off from a commercial airport, with an adjacent and hot TOR targeting system?
While this may be an accident, and will be called an accident, it also may not have been an accident.
