I saw a helicopter flying over California recently that could be heard within about 500 feet or so, as it passed over. Beyond that, you couldn't hear
The US has had noise cancelling on their special forces choppers for years. I seen a Pave hawk flying towards me up the Florida coast at night, not a
big deal as the Coast Guard flies them up and down our area all the time, then it turned out to sea and like someone had just flipped a switch it went
completely dark and silent, from maybe 1/4 mile away over the ocean.
No lights however you could hear a light wisp of the blades so I could hear that it was still flying. Made my jaw drop, I was waiting to hear it
smack the water but it kept flying out to sea.
Either the special forces were training out of the base near us or the Coast Gaurd has had this gem installed so they can sneak up on drug dealers.
