Sky News Mistake

At the top of the hour (8pm) as the announcer was saying 'Sky News with ....' we saw the floor manager or someone, put a glass of water on the table, he then quickly got out of camera view

They've been having some awful problems today!
First of all the fake newsroom shot turned a flourescent green during World News.
Then in the afternoon something the entire newsroom went black and there was nothing until it faded up again!
lol

I remember seeing something similar happen on ITN 545 (or had it moved to 540 by then?) a few years ago when the presenter was reading a report when suddenly the backdrop disappeared and was replaced by the plain grey background... I was quite surprised (but then I was very young at the time... I'm only 19 now!)
