I have spent the better part of the last week thinking of Ken Hadden and his untimely, and extremely disturbing death. I understand that Ken departed the airport and performed a reverse Half-cuban with a half snap(in place of the half roll) on the 45 up. I don't want to debate the issue of hotrodding or showing our ass. Right or wrong, we've all been prone to let our ego exceed our common sense. I am concerned that we often don't properly "prefly" and/or think before we fly. I have been called on the carpet once or twice myself, and the people explaining the error of MY ways also confessed their own errors and related the events as happened to them. Those who have climbed to the highest ranks of our sport have screwed up before, too. If I had intended the same manuever I feel Ken would have pulled me aside, questioned my intentions,and EXPLAINED why it wouldn't be a good idea. He might have even compared and contrasted the Reverse Half-Cuban as opposed to a conventional Half-Cuban. I believe Ken would have talked with me through my entire proposed flight and explained the potential hazards. It would probably have gone something as follows: Ken: NO, NO, NO, NO, NO, NO!! You don't want to do this! And I'm going to tell you why! Scott, If you are to begin a figure immediately after departure and you can't dive, the MAXIMUM airspeed you could possibly attain would be your airplane's max level flight speed at full throttle. Since you have a limited amount of runway length, which is grass, you probably won't even attain that airspeed. Second. Why do you want to do that particular manuever, and why do you want the same entry/exit altitude? If you use a looping/rolling combination to perform a 180 degree change of direction, at some point in the figure the airplane must be verticle. Either nose up or nose down, and the choice is yours! With a Reverse-Half, you start with a 45 up line. The half snap in the middle is going to eat up any energy that would help you to gain altitude. On the subsequent float and pull, you are going to bring the airplane's attitude to a verticle down. At this point you are totally committed to completing the manuever as intended. If you perform a HALF-CUBAN, you will pull the airplane UP through the verticle line and float so not to pinch the 5/8 looping portion, continue to gain altitude, and never commit yourself to a verticle down attitude. You will have more time to assess your ALTITUDE and you can very easily make the 45 down shallow, and half-roll instead of half-snap. If anything goes wrong, you are high, with the critical part of the figure behind you. You will have more time to correct any error or to address any problem. Most importantly, you are not as likely to place yourself in a critical altitude situation! Ken could have changed the mind of the most self-centered, egotistical adrenaline pumped person and made him or her feel good about it. I sincerely hope that I have not offended anyone by writing this, most especially Barb. My intent is not to question Ken's thoughts, but for everyone to question their own before ANY flight. If Ken Hadden could make this error in judgement, any one of us could. Their are many, many people in this sport who have a great deal more knowledge and experience than me. If I am wrong or out of line, please respond either publicly or privately. I haven't been active in IAC for two years and I miss it dearly. A few weeks ago DW commented about the loss of so many friends and aquaintances over the last several years. I agree, and am saddened that we have added two more to our list this week. Yet I still look forward to buying another Pitts, and rejoining the comraderie of the contest environment. I hope to see a lot of familiar faces! I just really wish that Ken could sit around and tell us how he "rolled that goddamned airplane up in a ball" and how we (and he) don't need to do improvised airshows!
