“The quality of any picture is related to the size of the object on the imaging medium and the amount of atmosphere between the object and the camera.”
Do you get my point? UFOs follow a specific pattern of always being far away in order to explain the bad quality of the photograph. When people claim to have seen a giant UFO hovering directly overhead they never seem to have a camera of any sort with them, not even a cellphone. Should make anyone skeptical.
People really don't expect to see such things, so they just aren't prepared. Many times, those who do, simply do not think of a camera. You presuppose that people remain calm and deliberate in those circumstances. They don't.
I've yet to see a picture of a C-130 Hercules right over my house, or even a Blackhawk.
If you researched just a little, rather than reacting in a knee-jerk manner, you might be surprised at the evidence available.
