Nope, more after Max-Q but not right before MECO. The smoke/vent of it looks happening on the upper parts of the Falcon-9 but of it is the second stage or the first stage (or maybe even the Dragon self) isn't very clear to see. In my eyes, it looked more like a structure failure what did leaking fuel much in seconds, what leading to a explosion.Was it just right before MECO?
It did look so far on a nominal flight, nothing really odd happened besides maybe a burning spot on the first stage around Max-Q on the first stage, but the explosion did happened around the upper parts, so I don't know of that can be linked.
