SM4 Pirate,
It's a pity that Dick and his mates aren't introducing ICAO airspace, because an ICAO VMC Climb (or Descent) requires the approval of the other aircraft. So the PA31 would have had the right of veto. And interestingly, ICAO only permits VMC Climbs and Decsent at or below 10,000ft. So much for international standardisation.
Coral,
I'm a fan of Mikes (well, I've been to lots of his presentations). Speaking from experience, all I'll say is, don't believe anything he said in the Oz.
