Although it is not known when this footage was shot, on June 24 the Atlas V rocket was fired off from Cape Canaveral Air Force Station.
The rocket was fired into orbit loaded with a Navy satellite.

The reason why this is 'normal' and 'not normal' at the same time is that it is basically something mundane (the Atlas 5 rocket launch from 2015), BUT the atmosphere's composition has changed over the last couple of decades or so, which means that things travelling through it often produce weird contrails. Climate change is real (and no, it's not man-made).
