My first trip in a helicopter was in a 500c as an observer in the early 80s on a jump drop at a major skydiving event in Australia. I was young and before my helicopter training. That sowed the seed for my aviation obsession...
Years later I dropped skydivers a few times. First drop as a young CPL-H over western Sydney from an Enstrom. Only 2 skydivers but good briefing by the chief pilot made the job easier. I agree, they (the skydivers) don’t listen, or follow instructions. Being ready to reduce collective and prepare for the roll left when the jumpers left the ship. REALLY important that they didn’t push off. My brief was very clear that they must just “fall” off the skid.
All went well but some 30 years later, that flight is still a clear memory.
