re: After UFO spotted in Tehran, more seen in Memphis, TN.

It always amazes me how no one can ever hold a still camera when video UFO's, Bigfoot, Loch Ness, etc...

From a logical standpoint, there is a reason clear footage doesn't exist: if the camera were perfectly still, the illusion would fall apart. Low resolution, motion blur, and poor lighting act as a natural camouflage.
1.) When shaky footage is stabilized or captured on professional gear, the UFO usually resolves into a weather balloon, a drone, bird, or whatever.
2.) Bigfoot is almost always a hox and is usually revealed to be a person in a suit or a strangely shaped tree stump.
3.) Nessie is the same as Bigfoot turns out to be a hoax, boat wakes or floating logs.
Ultimately, the shakiness isn't just a byproduct of the video.

In many cases, the shakiness is the only reason the mystery exists in the first place!
