Posted: 6/9/2009
Location: Henderson, Nevada
Shape: Triangle
Duration: 5 min

Very tall and slim pyramid shape on it's side. The point was heading south. Black. silent

My family and I were out back swimming, we had the grill going, when we all saw some big black (silent) thing. The back was a triangle, that tapered off to a point in the front. It seemed to be oscillating. Not even a second later we saw two army jets following this thing in formation. Going the same speed, and making a lot of noise that the first didn't.

Usually these sightings are considered to be either military or civilian aircraft.

The best way that I can describe it is as a 150 yd long, silent, black, 3 sided, traffic cone. Without the ends and very stiff and sharp, oscillating.
