Revoking ratings does not necessarily impact safety. Raising awareness of a known safety concern and taking positive action to educate those associated with it is the proper course of action. If the approach of revoking ratings for trying anything new was the standard in skydiving and aviation, we may not have many of the new dimensions of flight that we enjoy today. I know there were days where formations, freeflying, and swooping were all considered crazy. Perhaps we need to really look at what allegedly makes this style of tandem jumping unsafe rather than speculating. I would have to believe that with the number of people out there who have done unusual attitudes and stunts while performing tandems, we would have at least had one injury or fatality that could be directly related. I also know Jacko well and can concur with Jono's assessment. Perhaps we should focus ourselves on those who are dropping people out of harnesses and why those harnesses failed rather than trying to pull the livlihood of those who are obviously proficient at what they do. I openly admit that I have learned from many mistakes along the way in many disciplines. I am a better person for it and I pass that experience on to others. Many others benefit from the learning we get from making mistakes. There is an old saying in aviation: "Learn from the mistakes of others as you may not have time to make them all yourself". I encourage all who are reading this thread and concluding that a revokation of ratings is the proper approach to reconsider and write the USPA and the rig manufacturers to send an advisory of the safety concern and corrective action so that we can move forward with sharing our skills and knowledge. What ever happened to the skydiving community?
