I have no desire to enter the discussion on the value of parachutes vs. rappelling. My only point in this post is to point out that the best ideas, even amongst those who are rescue trained and "educated"; can not only go wrong, but maybe faulty to begin with. Most enlighten rescue instructors will recommend performing the white/black-board test first. Using one' knowledge, research and experiences; develop a plan of action, knowing the limitations of systems, equipment and personnel will allow for the theoretical establishment of the plan/system. This plan or system is then tested under controlled conditions. Lastly, the plan/system is put into practice through training, continually evaluating and updating/tweaking as appropriate. I do not know if any of the other "rescue heads" out there have had the opportunity to see the Virginia Beach Fire Department (they are a great bunch of guys and gals- well versed in technical rescue) training video of their attempt to create a continuous loop high line system for large scale evacuation of the numerous high-rise hotels located in VA beach, but after viewing it, one quickly realizes that it was not such a great idea when put into practice. The video shows the rescuer slamming the pavement at a fairly high rate of speed. The idea was noble, but it required more white/black board analysis. <img src="images/graemlins/confused.gif" alt="" /> For those looking for a solution to any emergency/rescue problem, even if you yourself cannot "test" the plan/system out, do your homework, get several alternatives, read what the "experts" have to say and then examine the success and failures. Ultimately you will have to make your own decision, but at least it will be an informed decision. <img src="images/graemlins/grin.gif" alt="" /> Pete
