I fly in Seair Caravans (and Beavers) all the time as a passenger - have done for years. They are a great company. I'm a low time PPL so I often sit up front to see what I can learn from the pilots. These guys are total professionals, and highly experienced (36,000 hours in one case, although sorry, all as a VFR liability!). The photo above looks like very typical west coast conditions, and most of the Caravans have glass cockpit, terrain warning, collision avoidance etc. There are survivors with evidence to give, so let's not jump to conclusions about cause or pilot skills.
