What's interesting and fascinating about it is that it contains video from a cockpit camera that shows the impending mid-air collision and the cockpit view when the aircraft hits the ground under the chute: http://www.turbopilot.com/copa/image3/brs.wmv I guess cockpit cameras are becoming common enough that this sort of video would be inevitable. (Not sure why the pilot didn't see the towing aircraft - unless it was because the other plane was coming up from below to his right.) I don't know what it is about that site, but my firewalls and blockers will not accept it. At least one of them has it on the blocked list.

Further followup with a bite more info: Here's what appears to be the full cockpit video from collision to touchdown: They called it a "near collision. Unless the other video shows contact this one does not. They appear to be about 30 to 50 feet apart. Did they or did they not collice? http://www.youtube.com/watch?v=v_JAg1ZedGo This site I could get to with no problem. My question is, "why pull the chute" if they didn't collide, I don't see any reason for the chute excpet panic. According to the comments, he was flying a Rans S6. Also, the CNN video was also posted to YouTube, and based on the dates of those postings this appears to have been reported back in December (around Christmas) of last year.

Aircraft can be incredibly hard to see, believe it or not..... In this case, perhaps it is possible that the tow-plane was in a blind spot where the Rans S-7 pilot couldn't see him? If one assumes a plane on a collision course appears to hold roughly a steady bearing, then the tow- plane would have been visible to the Rans pilot several degrees below the horizontal (the tow-plane appeared to be climbing as it passed in front, left to right) and somewhere off to the right - the cowling or camera(!) blocking the view of the other plane. And then there is all the ground clutter the pilot in the higher plane has to process to see anything lower that also happens to be nearly stationary with respect to the scenery. So (and this is all speculation of course!) it seems to me the tow-plane pilot might possibly have had the better view to "see and avoid" - since there were no less than two planes above his altitude that he was heading toward. |

But leaving an event up to chance as the avoidance mechanism, is not something that sits well with people. I have to feel that way, in that the results of "winning" the odds are so dire. Absolute agreement. To me, it's a good reason to be "heads up" when flying over VORs, since they can really concentrate aircraft. Most of us are spending more time on the gauges watching for the arrow to change. I see more aircraft close to VORs than any other place except in the traffic pattern. When you are headed one way and opposing VFR traffic is only 500 feet above or below if they are right on altitude they look *CLOSE*. :-)) Still, maybe it's a non-issue, since we don't seem to hear of lots of collisions around VORs. Seems like mid-airs are mostly around airports. Anyone know the real stats of locations offhand? I don't have any stats, but from what I remember in the news in recent years "it seems" as if most mid airs are close to airport. OTOH there are some outstanding exceptions such as the two jets last fall or summer down in South America.

Why pull the parachute? Just speculating, but when he ran into the tow rope it definitely shook the plane bad enough that it moved the camera around in its mount (or may be that the pilot knocked the camera when he cutoff the engine). It appears the prop cleared the tow rope and he didn't lose any control surfaces, in fact it looked like he was gliding in control for awhile before he pulled the 'chute. He even sounded like he shut down the engine, that the engine didn't quit and it didn't sound too rough like it was misbalanced. First, the pilot (and reporter) said in the CNN report that the prop struck the tow rope. Secondly, consider the following: In the "original" cockpit video (link quoted below), it sounds like the BRS rocket is fired at about 11 seconds into the video and the plane hits the ground at about 51 seconds into the video. Assuming nothing was cut from the video, it took about 39 seconds to descend under the chute. The BRS web site says descent rates are typically between 15 fps and 28 fps at 5000 ft density altitude. That puts the altitude possibly somewhere in the range of 600 to 1100 feet agl. The Rans web site lists the glide ratio of the Rans S-6 at about 9:1. So the pilot would have had between 1 and 2 miles of best-glide distance to find a good landing spot. I don't know what the best glide speed of the Rans S-6 is; I'll guesstimate 60 mph. That gives the pilot between 1 and 2 minutes of air time - absolute max. Decision height for the BRS is around 300 feet. Given the altitude, unknown condition of plane and insufficient time to determine the extent of the damage, the decision to deploy the chute was, in my very humble opinion, the correct one. It is just the sort of situation that I believe ballistic chutes were originally designed for. I always wondered if the availability of such a device made for more accidents or less. It sure sounded like a rather solid landing! He did walk away though. I most definitely disagree - the parachute no more caused this accident than the pilot's seatbelt did. Solid landing perhaps, but as the CNN story mentioned, not only did the pilot walk away, he was able to rebuild his plane - with of course a new chute. The end result appears no different than a typical successful emergency landing where some damage occurs. Bart D.
