WOW!!! Just Saw The Coolest Thing I Have Ever Seen. Squadron Of Unknown Type Craft Just Flew Low Over My Head And Could Barely Hear A Thing

A squadron of what I can only describe as curved delta wing craft just flew over my house at about 5000 feet I estimate. There were 9 of them flying in V formation. The cool thing was when I first spotted them I only saw 5 of them. But when they flew directly overhead I saw the others that completed the V and they looked like they were camouflaged to match the cloud and sky. It almost looked like it was projecting what was behind it on the bottom of them but you could still see the outline of them. It was fucking amazing. As low as they were I cannot believe I barely heard them. It sounded like a couple of cars going down the road that was it. Simply amazing. They looked like they were gliding more than flying. It's hard to describe. Obviously our tech as come a long way.
