Have I correctly understood that the go around was caused not by a runway incursion, but the lack of a landing clearance due to coms failure or whatever?
Surely if you can see the runway is clear, and you have no other indication that you are not cleared to land, captain's discretion would dictate that a low level GA is not the safer/best option? I'm sure it would also have prevented the ignorant ravings of Mr Katter and the like.
On the positive side, I am so pleased that the pilot did in fact decide to switch the throttle on prior to going around - especially when they were so close to 'bumping down'.
