June 1988. So synchronisers well established and so surprised to see non-sync cuts to outside sources. ITN was permanently fed to LWT (and Thames) so it was permanently sent through a synchcroniser at LWT to make it sync to Presentation.
LWT News was produced by a small facility house somewhere in central London by ‘Screen News’ and was fed, as normal, via another incoming circuit to LWT as required. It too would have been fed through another synchroniser to make it sync into pres. Would two different synchronisers have both been fed with a pulse source other than presentation? Unlikely, but clearly something not right.

It was a trail so would it have been put to air directly from the facility house, or recorded at LWT and played out from there? Just thinking that the thing that was non-sync was a VT machine that played the news trail, maybe a set up put in for a quick turn-around of a trail and not installed to the normal kind of spec.
Normal caveats of course that the picture disturbance looks a lot worse on the recording ham or would have done on a TV set at the time

The local news trails were live. Thinking about it we see a transition from the incoming local news trail direct to ITN so in fact it is very likely only the incoming local news feed was non-sync to presentation. ITN would have been synced to Pres as normal but it only takes one source to be non-sync to get a disturbance either end of the transitions.
By the way, local vt machines performing transmissions were always lined up level and timing wise into pres, if they were on the wrong syncs there was kit installed that would show that straightaway (designed in-house by LWT engineers).
