At long last.

At long last, the smashed windows on the J type, well to tell the truth, the glass was removed and replaced with sugar glass for a stunt on a TV show.
The episode has only just aired on TV despite the filming done nearly a year ago.

 Near side cab window, camera panning down to the dead body in front of the van.

 Short fight, man runs into side of the van, trying to run away.

Nice aerial view of the body, note hole in windscreen, and displaced number plate.
The whole episode can be watched again on the excellent BBC1 iplayer.
