A very good video. You are very lucky! This example of an AS350B-3, operated by Pellisier, is a really lovely aircraft. I couldn't help but think that it was cheapened by a really crude home-made plywood 'floor protector' in the rear cabin and those zebra-print seat covers. At 15:25, you undid your seat belt, just prior to landing - the most dangerous phase of any flight. A really foolish and inconsiderate thing to do. Had there been a heavy landing, your unrestrained bulk could have been thrown across the cabin, incapacitating or even killing the pilot or other passengers, who would have, otherwise, survived the incident. Wait for the pilot to say when the belts can be released - or at least let the skids settle on the ground first!
