Friend of mine flies a gorgeous Global Express worldwide for a huge entertainment company and frequently encounters problems with slower 747-400s, 777s and A340s at altitude.. .. .Operating at altitudes of 430 and above he gleefully looks down and zooms past the bigger but slower traffic... He also earns $200K per year - not a bad job.... .. .It's the damn "put up with my slow aircraft" attitude that I HATE! If you are slow, be courteous and get out of the way if possible.... .. .Cheers
