I agree with Gonzo on several parts, the video is clearly edited so the full facts aren't known and any safety incident should be reported regardless of how trivial you think it is. I also have issue with the childish remarks made by all the other crews. Certainly think them, never say them. That man they are winding up and raising blood pressure is about to fly an aircraft. It is good for all the other pilot sakes that no further incident took place otherwise they could be noted as a "casual factor" on the investigation report.
It's very easy to point the finger, but at least do it with all the full facts in place first.
