Drag King - it's not the tonnage, it's the requirement for multi crew. Whilst the pilot of a single pilot aircraft is certainly the commander it is pretentious to call yourself "Captain". You are only in charge of yourself. It also implies a broader experience level and even then, you are only a captain whilst working. Lastly, whenever an individual uses the title "Captain" I get an uneasy feeling about that person's competence. To date, my gut instincts have not been let me down.
Me? I'm just a pilot.

To be fair to this guy he should advertise that despite several near misses, a few crashes, regularly flying on fumes, using MS flight simulator for flight planning! upsetting many people, etc. he's still alive - and that is an amazing achievement.
