Glibness aside ...
Some of the smartest students in the world go to Hillsdale. Hundreds of students saw a UFO — I forget if it was in the 60s or 70s.
I imagine this would be a good site to check for mass witnessing:
UFO Sightings Worldwide

I had assumed that cameras in i-phoes would have found plenty by now. But maybe as our technology advances, they get more camera shy? Heck if I know. In all seriousness, I think there is intelligent life out there. And it concerns me that leading figures such as Louis Farakhan are openly claim they are taking orders from E.T.s.

THANKS THANKS.
Most UFO sightings are so fleeting that if you don't just happen to have your camera in hand and at the ready, you probably won't get the shot before the thing disappears.
A lot of footage of UFOs is captured by people who are in the process of filming something else when a UFO comes into their field of view. Sometimes folks don't spot the UFOs in their footage until they review it later.
Also, cell phone cameras have pretty bad resolution on average, and do a poor job of capturing detail even close up.
