Taking off with 1 pax and a copilot shouldn't make even a 20 kt tailwind a concern when you're that light. Some places you'll go into are one way in, one way out, tailwind takeoff and yet we sure as hell take a good payload out without risking lives. I heard the pilot was holding the nose up on the takeoff roll, which is the norm... but he was lifting the nose way too much = too much drag... a royal f*ck up. This the same guy taken off with pod doors open... so i'm not surprised!
