This is an interesting analogy. As a diver I've long drawn a mental parallel between the dangers involved in diving depth and the dangers involved in driving speed. Interestingly enough the parallel is about 1 fsw == 1 mph. I view the risk of diving to 15 feet to be similar to the risk of driving 15 mph (minimal). 60 fws/mph is comfortable and safe. 100 fsw/mph is approaching the high side of comfortable cruising. 140 fsw/mph is moving into the danger zone. 180 fsw/mph is the upper limit without specialized equipment/machinery. 200 fsw/mph is running on or beyond the ragged edge. Of course with the right equipment/machinery those numbers can be exceeded with reasonable safety but this moves beyond the realm of air/street machinery. And of course in either domain there are those who are so good at things that they can readily exceed what the rest of us mere mortals can do. Just an observation. > Tim Payne Eric Marsh
