The only thing missing from the media reports is "pilots fighting with the controls, while passengers screamed in terror". No, there weren't 18 people on the one aircraft as the media tries to make it appear.
One pilot whose navigation competency is highly suspect makes some serious errors and gets lost - so that translates to "a major incident that could have dwarfed Lockhart". The entire beat-up hinges on "could have".
It is no more newsworthy an event than the dozen other incidents over the last few years, where someone screwed up, and a potential mid-air was possible.
I trust this King Air bloke gets his competency reviewed, it sounds like he barely scraped over the line when his licence was first issued.
