Hi hon, I am so sorry that this accident occurred, it is truly a nightmare - I am a student diver so please forgive my interjection into this topic. There is an excellent on-topic article in the April 2009 issue of Dive Training Magazine "The 4 W's of Guided Dives - What, Why, When & Where" . (Page 22) Besides being a student diver, I also hold my private pilots certification. I have also worked in flight test, and witnessed several crashes of experimental military aircraft (I don't recommend doing that). I am using this terrible incident as "lessons learned" and am adding it to my knowledge base, so please understand, that Brendon did not die in vain. We must non-judgmentally and without emotion (as much as possible) - review the incident in the same way that an aircraft incident is reviewed. What I am hearing seems to be the same as the initial (probably 90 percent) initial finding, which you may have heard repeated ad nauseum in the news - "pilot error" However, as an accident is investigated over time, other factors begin to appear. This has a direct parallel to diving. ....... In a typical scenario (lets assume that this pilot has 40 hours logged, so they are a new VFR pilot), The aircraft is a rental, (being flown out of an unfamiliar airport) perhaps the first thing that occurred, was that the pilot took off in degrading conditions (talking about civilian not military for this scenario)- the wx report said that conditions en-route and/or at destination were ok, but the departure was a little shakey, maybe a little closer to marginal than the pilot was used to - no prob, just get airborne and everything will be ok.... Maybe in a little hurry, so the preflight of the aircraft was a little rushed, and the ground runup gets shortened - gotta get going before the weather starts to sock in, and hey, a nice dinner is waiting at the destination! Lets get go'n! So off they go into the wild gray yonder..... Now, about 100 miles out, our VFR pilot starts to encounter chop and the ceiling comes down..... The work on the radio starts to increase pilot loading - do they abort and try and head back or push on? More chatter with ground controllers (pilot task loading continues to climb, stress increases), and the aircraft oil pressure is bouncing around a little bit, maybe more than they are used to seeing, just a few psi...... not bad, just little bumps.... Now the sweaty palms start - can't climb over the crud, (VFR pilot) so better get beneath it..... Picking up a little ice (ice wasn't in the pre-flight weather briefing!, but there it is on the leading edge and the windscreen) - because of stress and increasing pilot load, forgets to pull on the carburetor heat...... now the engine starts to choke up with an iced carb - rpm falls, our pilot now decides to make a 180 and head back, and diddles around trying to figure out why the engine rpm's are falling)....... they make the turn with increasing bank angle, with marginal ice on the wings, until the aircraft stalls and spins in. In the investigation, where does the pilot error begin? No SINGLE event caused the crash - but the real killer was pilot task loading..... Although this pilot was in command, and did nothing against the Federal regs (FAR's) the accumulation of events did them in. The weather was ok, but the weather and the ocean have minds of their own - The aircraft was ok, although it had a small oil pressure anomaly, their training was just fine, (although their total flight hours were low) the area was unfamiliar, but they had a briefing by the fixed base operator (FBO).....
Now back to the Cayman's - Their is an almost point by point parallel of the Cayman accident to a typical aircraft incident. It is not one single event, it is multiple events in a positive feedback loop. And guys please forgive me, but I must reiterate a statement made elsewhere in this thread - another contributor may have been the male ego. When in an aircraft accident occurs that indeed is truly pilot error, the male ego is often a contributing factor (sorry). His ego may or may not have been a contributing factor, but dollars to doughnuts, it was. Their are many dispassionate lessons to be learned from this accident, and I intend to learn from it, just as I have learned from studying aircraft accidents.
As you may be able to tell, I treat diving exactly and precisely as I treat flying, their is NO difference, except the "ether" encountered - the ocean or the sky. They are both intrinsically foreign to humans........ we are neither birds nor fish, and totally reliant on our equipment and our wits to allow us to function in these foreign environments.
ya' know, in flying their is a saying that is equally appropriate to diving - "There are old pilots and their are bold pilots, but there are NO old, bold pilots". My heart goes out to Brendon's family and friends .......
