It's all well and good to say that one should never get into IMC unexpectedly, but it seems Rotorspeed hasn't had that much experience. Sooner or later it will happen. I was once flying a 206 loaded with tired roughnecks down the beach under a 700' ceiling, with 10 miles or so of visibility, no worries, when the sky just fell on me. The clouds simply opened up and with no warning visibility was near zero in heavy rain and high winds. I immediately made a turn, trying to keep the ground in sight, but the turn didn't help, and I ended up doing a 360 back into the wind and landed on the beach. Half an hour later we continued on. More times than I want to think about I've had the skies dump on me, visibility go to nil, and there I was, saying "Just let me get out of this alive and I'll never never do it again!" Good pilots keep having it happen, and many of them don't survive it, so it's obviously possible. Sticking your head in the sand and saying it's entirely preventable is just silly, IMO. It happens, and one has to be prepared to get out alive. Certainly caution is one of the main ways to live, but more is needed.
