Very strange sound heard sounded as if it had a melody.I was getting ready for bed at approximately 10:00 pm, when I started hearing a very odd sound coming from the sky. It was definitely not any plane or helicopter I've ever heard it sounded like a plane descending kind of humming whistle but it was constant and almost sounded as if it had a melody to it. Doing what any one would do if they heard something strange like that I walked outside to investigate I couldn't see anything but I could still hear the sound it sounded as if it was coming from everywhere at once. I tried recording the sound but when I played it back you couldn't hear the sound (the recording device has bad audio). Around ten minutes after trying to record it with no luck I went inside to get online and see if anyone else had heard the sound and my internet froze just completely stopped working. It wouldn't come back on until the next day I usually don't have internet problems so that happening is very uncommon. At around 10:25-10:30 pm, I heard at least 4 helicopters flying over the area they hovered over the area for at least 15 minutes before dispatching. I walked into my living room and asked my sister if she had heard the sound she told me she muted the TV because she thought she heard a really weird melody coming from outside but didn't think much of it... she is not as in to the UFO scene as I am.Although I didn't see anything that would say UFO, I definitely heard something very strange and simultaneously lost connection to the internet which is in my mind definitely proof of something. I've had a couple experiences with UFO's in my life, but none as strange as this this sound was not from any mainstream aircraft. It could of been a HAARP test but I don't know I am mainly posting this to see if anyone else has heard something similar.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
