Modelman - your post sounds like the frigging thought police. I go flying to get away from people with that kind of attitude. If you were a CFI or other high hours then such an observation is fair enough if they judge it was too low (contravention of Rule 5)..... but as a student I think you should keep such comments to yourself ! I have no doubt they were above 500' and if they have the ability to fly in formation then good luck to them .... what fun! Who are you to judge? I strongly suggest you concentrate on your own skill development and think twice before ratting on fellow pilots (when you become one that is)
