I have seen 2 QF skippers lose face to date. Unfortunately it does happen and they do chuck a nasty tantrum, what makes it worse is that 1 is in the training department. Luckily Safety of Pax was not in question over the incidents, just a 4 bar wearers pride.
Its Rather shocking seeing 50 year olds chuck tantrums. Now i know how my old man felt when i was in that early teenage and younger years stage.
