This was captured while hiking on a hill at sunset, i was midway to the summit ( the hill is 510 meters high ) when i filmed this, without being aware the object was in it, until reviewing it later.
It covered a distance of about 3-4 kilometers in 3 seconds ( that is at speed of approx. Mach 3 ), and was flying very low, without any sound, while most jets that fly in that area fly much much higher, and way slower.
I didn't notice this craft while filming it. all the jets and planes in this area are much slower, and fly much higher. Also you could see in the footage that the object has no wings or tail, and has a perfect cigar shape.
