    Someone explained this to me but I may butcher it. The vapor clouds you see are actually the airflow over certain parts of the jet going transonic, the jet itself is subsonic so while it’d be extremely loud, it won’t generate a sonic boom.

    A. This doesn’t look real.

    B. This layer stays with the plane as it pushes subsonic air into supersonic. So it is the moment, that particular space of air goes supersonic, not the jet itself.
