Globaliser, if you're talking about the DXB-LHR Heathrow Penta go-arounds, I believe you may have missed the point.
As for the rest of it, I don't believe anyone would disagree that pilots who either deliberately or recklessly endanger their aircraft, cargo, crew and passengers should be prosecuted. Negligence is, in the circumstances of our industry, criminal.
However, nobody should ever be put in fear of their careers for making a mistake.
The big question, of course, is where does "mistake" end and "negligence" begin? A pragmatist would argue that the courts should decide this. But a jury of lay people won't understand anything about what goes on in aviation. So what's the answer?
