Nick Roesler on "We Are Not Alone" -- 1pm, Tuesday, March 2

Nick Roesler, MUFON photographer and author of "In Focus: Photographic Evidence of Unconventional Flying Objects", is Host David Twichell's guest this month.

With today's photographic computer software, UFO hoaxes are easily created. However, in the right hands, that same software can detect those hoaxes.

Roesler discusses how an expert tells if a photo or video is a hoax, a misidentification, or genuine. He also talks about vintage photographs of UFOs, taken before the advent of computers, which have stood the test of time.
