It's just amazing how uninformed you guys are. What you were watching is huge. You should acquaint yourself with some of the data.
Just to prove how little you know, did you know that Art Bell and his wife, who live over the hill from area 51, were out walking at night one time and a huge black triangle soared over their heads without making a sound. All they could see was the triangle where the stars were missing as it passed by. Hehe, see there's proof.
On a more serious note, the black triangle has been reported all over the place many many times. I really don't think people are making up these sightings. What they are is the question, and why people don't hear anything is what makes me especially curious. Can sound cancelation work on the scale of aircraft. Is it an electric blimp? The truth is out there.
