My guess is that the stolen passports attempted to hijack the plane and then there was a fight in the cockpit, like flight 93.
Straight into the ocean like a dart.

That would explain both the lack of radio contact and the lack of debris field.

Would a black box show whether this happened?

I think there’d still be evidence shown to traffic controllers of the aircraft’s descent. Apparently, it just disappeared at 35,000 ft. altitude. My current theory is what most suspect; A huge explosion at altitude.
