Casebook:

This is a chronologically sorted list of all the cases mentioned or thoroughly documented in this site. This is not a list of all UFO observations: there are dozens of observations every day all over the world, a part of them are simply not true, other are misinterpretations in good faith of natural phenomenon or aircrafts and satellites, a respectable part has no better explanation than extraterrestrial cause.
