With all the camera phones that can videotape picture perfect pics, shouldn't we be seeing a lot of UFO's by now? Or have the "Aliens" adapted to our new technology and went much more stealth?
Considering most sightings are at night you won't get many high quality videos.
The UFO sighting is usually a bright light in the black sky , moving rapidly or erratic.
Plus you have to be looking up to catch a few sec.
Think about it like this:
There are numerous plane crashes around the world.
How often do they get filmed at the time of the crash impact?
