I didn't see a mid-air explosion in the video. I saw what appeared to be two folks ejecting, one before the other.
Correct
“The videos show one of the planes flying vertically before a pilot is ejected...”
The main video I watched was when the plane appeared to level out, now coming from the right to the left, and both pilots ejected leaving a smoke trail from the egress. I was a little curious how the angle of the egress was relatively flat like they didn’t eject away from the aircraft but kind of got mostly clear as the aircraft started down. So as far as I can see, they knew there was no way to gain control of the craft and bailed.
That could have been mechanical or computer failure like aeronautics or the power source. They did have egress so it wasn’t a total shutdown. Lots to take into consideration here.

“I didn’t see a mid-air explosion in the video.”
Depends on which videos you see...right now. That’s one of the main headaches the TSB will have as they are working with so many turned in videos. I think the trail from the second egress is what some people are interpreting as a midair explosion because it came briefly later than the first. But it is another possibility so it has to be considered and, we both feel, disregarded. Kind of the old all in good time.
