It’s been done many times over a period of many years. However, as most of these jumps were what are known as “bandit” jumps meaning without all approvals in the given countries, you won’t find them on YouTube as it would endanger the given pilot’s license.
I’m a skydiver myself and have made several helicopter jumps from ships such as R44, EC120, AS350, Alouette & Lama. These are common scheduled jumps. Some may think that they just go to a few thousand feet for “hop & pops”, but that’s not correct, for example, my single squirrel jumps went to 11,000 AGL in Switzerland.
You’d be surprised at what has been jumped or is regularly jumped. Everything from Pitts Special (pilot does loops and you hang upside down by small T-Bar in front of seat then let go – to the prior regularly scheduled jumps from a DC9 at Perris Valley.
