To summarise...
What is a UFO?
UFO stands for 'Unidentified flying object'.
However, the term UFO is not used by scientists anymore due to its association with 'extraterrestrials' or 'aliens'.
The new term is 'UAP' which stands for Unidentified anomalous phenomena.
UFO's are almost always explainable!
