No more facts than I have to conclude beyond a shadow of a doubt that it was a terrorist attack.
Unlike you, however, I have over the past few years developed a healthy distrust of anything NewsMax reports.
However, the real world evidence (the snapped-off stabilizer, the corresponding rudder deflections in the flight recorder data, and the lack of evidence for an explosion, as even NewsMax's lame article is forced to admit) lends credence to the idea that it was more likely an accident.
They do still happen, you know.
