Skepticism, Science & Pseudoscience

Years ago, when I paid more attention to this stuff than I do now, there were always a few that defied any explanation. The question was then, as now, when will an explanation show up? If ever? And no explanation just meant no explanation, not that aliens were involved.

The triangles, though, woke me up. If anyone sees the bow wave (or whatever it's called) of an aircraft attaining supersonic speed, it is a triangle. I was thinking that the oddball filtrations being used could have made that wave visible. His explanation makes more sense.
