This is a well written, very thoughtful report. Well done. I agree with John. I also agree one solution is the 500' finish rule he's advocated. I don't agree it's the only solution or necessarily the best solution, but we've thrashed out that subject at length already so there's no need to again. I'll simply observe that part of the reason many of us fly contests is for fun and that the best way to eliminate the risks of flying is never to launch. What struck me about the report was that nearly all of the parties who might have contributed to this accident--the pilot, the organizers, and the photographer himself--could and should have taken steps to have avoided it. My impression is that had the rules in effect at the time been adhered to and enforced (whether those were CAA regulations or the contest rules or just general safe flying practices and common sense), this accident wouldn't have happened. I've never flown in the U.K. but I've seen comparable situations at many U.S. contests owing to (1) pilots emulating their fellow pilots (for all of our much-touted individualistic personalities, we can be like a bunch of sheep at times); and (2) the sense that because it's a contest, the normal rules for safe flying are suspended. These are serious problems, but they're problems of attitude. And the solution to them is not necessarily a new rule addressing one, albeit potentially dangerous, situation. The analogy is a little weak but as one example, we in the U.S. had a tragedy at a national contest a few years ago launching a water ballasted glider too close to bystanders. The solution to this dangerous practice was not to eliminate water ballast but to insist that all bystanders remain behind the launch line. It's certainly possible that a random hiker could be mowed down by a low-finishing glider but it's also possible that any of us could do the same thing landing out in a farmer's field somewhere. Should we, then, eliminate all practices that might lead to outlandings? Like most aviation accidents, there appears to be no single cause here, but rather a series of questionable decisions and actions that cascaded and culminated in loss of life. Without trying to fix blame, it seems to me that at any point any of the parties could have acted to comply with the aforesaid rules/practices, broken the "chain," and unilaterally prevented this tragedy. And now that I've offended almost all involved, I apologize for drawing conclusions about an accident I have no knowledge of apart from a report I had absolutely no role in preparing.

First of all let me add to others prior statements of what a tragedy this
was resulting in the loss of a renowned photographer as well as the certain burden it has placed on the pilot and families involved and the organizers. As usual Chip has thoughtfully remarked on what many of us have felt about racing and the attempt to make it safer. Most importantly is the idea that it is the attitude and vigilance of the pilot that is the primary reason all flights are conducted safely or not. No amount of regulation will overcome the poor judgement that some pilots exhibit. Having considered what has happened to others and with realization of the consequences it is our practice locally that we finish one mile out and if after doing so, wish to do a pass, do it down the runway after making several radio calls announcing our intention and asking for traffic advisories. If there are any conflicts we abort the pass. I do not think that the 500 foot finish is any safer for reasons that have been discussed here in the past. I also respect the opinion of others that disagree. Thanks for your thoughts Chip, Casey Lenox KC Phoenix |

This accident is a perfect example of something that
should never happen. The ultimate responsibility for the tragic death is that of the pilot concerned and no-one else. No-one held a gun to his head and forced him to fly so close to a point where he knew there were people, and it should be emphasised that this event occured outside the airfield boundary. Observant readers of the report will note that the silver car that the photographer was standing on was situated on the left hand margin of the extended landing area boundary which rather begs the question as to why the pilot of the glider concerned felt it necessary to bank to the left, with a bank angle of 20 degrees, which on the face of it would take him further away from the landing area. I do not have a great deal of trouble reaching a conclusion but it is up to you to make your own decision on that. The photographer was going about his lawful business in an area outside the airfield boundary, and it was well known that he frequently took such positions. He was an experienced glider pilot himself and no doubt trusted that pilots would have the good sense not to fly into him. I would refute any suggestion that he was in any way 'responsible' for the accident, his action may have been unwise with the benefit of hindsight but given the known circumstances it was not unreasonable for him to do what he did. Whether his presence 'encouraged' pilots to fly in the way that they did is perhaps a question that can never be answered, certainly by the pilot concerned. As to the future we are now in a position where the CAA could set the rules for competition finishes in the UK and they are not likely to consider the aspects of fun and spectator enjoyment in their deliberations, or at least place much weight on such considerations. I find the worm burner competition finish acceptable over an area where I have the control of the activity, it is good to watch and reasonably safe provided access to the area over which it takes place is controlled. No competition director has any control over what takes place outside the airfield boundary and for that reason a margin for safety has to be set. The safety margin that may now be imposed on us will probably be greater that we would like. Like the rest of life safety rules only have to be made for the information of fools, those who are aware of the possible consequences of their actions and are resolved to always take action to mitigate such consequences do not need rules to make them fly safely. Perhaps one way forward is to require that every pilot taking part in a competition comes with a certificate, setting out the minimum level to which they may decsend during a finish, from their CFI in the same way that aerobatic pilots are cleared to minimum levels depending on their competence, ability and experience. This at least would enable competition directors to receive some assurance instead of finding out to late that what is being done is outside the competence of the pilot concerned. It would not restrict those who are able to fly very low safely, avoiding a blanket prohibition which would in many ways detract from the spectacle of well performed competition finishes.

Observant readers of the report will note that the
silver car that the photographer was standing on was situated on the left hand margin of the extended landing area boundary which rather begs the question as to why the pilot of the glider concerned felt it necessary to bank to the left, with a bank angle of 20 degrees, which on the face of it would take him further away from the landing area. I do not have a great deal of trouble reaching a conclusion but it is up to you to make your own decision on that. If you look closely at the GPS tracks on Figure 5 you'll see that the accident pilot appears to have approached the hedge a bit from the left/South at less than a 90 deg angle/not perpendicular (see black track). An estimated 20 deg bank angle to the left is most likely a consequence of him making a slight adjustment/bank to the left to line up perpendicular to the runway/finish line. The accident report mentions that the pilot does not recall having conciously banked which suggests that he might have done one of those instinctive adjustments we all do when lining up for the runway, his primary focus appeared to have been on clearing the hedge (page 58). My humble guess is that he popped up to clear the hedge and upon seeing past the hedge subconciously banked a bit to better aline with the runway. Looking at the red and blue track as a reference he probably needed to adjust his track by about 10 deg to the South when crossing the hedge to line up the same way the other two competitors did. Looking at figures 4a/4b and how close he was to the hedge supports that he probably did not do a concious banking maneuver; had he been just a couple of meters or so further to the South (to the right in figures 4a/4b) he would most likely have struck the hedge with the wing tip and not the unfortunate photographer. Any concious banking maneuver should have triggered him to pull up more before banking irrespective of the cavalier attitude shown by flying this low in the first place. My humble two cents, Markus Graeber |

Just to add to another aspect of this accident report, the continuing
low approaches when competition officials radioed instructions to fly above 200 ft. Well, perhaps the pilots did it deliberately, but I'm not so sure. The accident report states: "The language used during international gliding championships is English and so all competitors should be able to understand such an instruction". I'm afraid that's rubbish. English is the only official language for rules, communication etc., but knowledge of English is NOT mandatory for the pilots. Many international competitors speak very bad English or even no English at all. I'm not assuming this: I was a ground team member in two world championships. Non-English-speaking pilots just learn the indispensable terminology for take-off and landing by heart (The same trick applies when an English pilot - who doesn't speak the local language - flies in Spain, France or Germany, for example). Their team captain translates the most important information from briefings and other instructions. The same holds true for the organizers, by the way. In both championships I was involved with, only some officials were able to speak English sufficiently fluently. I remember some security briefings where it was decidedly difficult to understand if some parts of the airspace, normally restricted, were available to the competitors or not! And communication between the organizers and the tug pilots was in local language only. Not exactly a safe situation... Please don't assume that everybody in the world understands and speaks English - or even "Globish". It just isn't true! |

Accidents don't happen by accident, and it is always sad to read about
the chain of events, which quite often, could have easily been avoided. WOW! The competitors kept flying so low, even after the mishap, that the rescue staff had to duck. Increase the risks, and you will end up on a report too... The picture on the contest cover is familiar. Was the photographer Hughes Beslier? http://beslier.free.fr/ If so, it is truly sad....
