RE: World Model Speed record???
Like michpittsman mentioned in his post, almost all, if not all aviation records are sanctioned by the FAI. You must meet FAI specifications for the aircraft and follow their procedures. All of the AMA records work through the FAI. I saw a picture of an SR-71 with a large white X painted under it. The caption noted that the mark was so the speed run could be monitored by the FAI.
