You can't 'clearly' see anything of the sort.
Couldn't possibly be reflection off the windows or skin of a jetliner, right?
It was going nearly vertical and then curved to the NW slightly. I have seen many launches and it sure looked like one to me. The smoke looked like it was from a solid booster. The satellites will have the track. and can estimate point of impact as well.
IF it’s a commercial jetliner (and it may be) it seems it would be an easy thing to tell exactly which flight it was.
