Looks like a Sikorsky. I flew EMS for the last 10 of my 40-years flying career, and landing on buildings was the most fun. Although it sometimes made the Medical crew a bit nervous. Especially when hospitals were doing some expansions and I had to dance around the cranes. UNC Chapel Hill was a blast when there was a Football game. The pad was directly behind the stadium. 😊

I always had to clear the pad and open the chain gate when we heard they were coming from la to Sierra Vista. blades are pretty low when they aren’t moving and hide your hat!

I really love the roof top take offs and landings. Not only that, I like helicopters with the triple flash strobe lights,....they make the helicopter look so cool to me. In addition, on this video a person can truly see how powerful those landing lights are. They light up the whole building when the pilot turned them on. Great video!!!

I have a video very similar to you'res of a Sikorsky s76D helicopter from Arkansas children's hospital taking off if you wanna check it out
