With regards the video editing and the go arounds, I've managed to speak to someone who was also spotting on the day and witnessed it.
First, there was a 2 minute "silence" from the BA guy after he was cleared onto the runway having claimed to be ready. This is when the controller replied "Oh negative ..." This was edited out as with liveatc.net at eidw, there is no sole tower frequency, it switches to approach etc during silences on one frequency. Therefore you would have heard 2 mins of unrelated ATC chat in between had it not been edited though i feel it should have been mentioned. This works against the BA guy further.
Next though, the 2 go arounds is absolute nonsense. The guy seemed baffled as to where that came from as there weren't even any aircraft on the approach at the time. Had it been true you would have heard them on the tower freq.
