Well, if they exist, aliens would drive them.
We don't know. That's why they are UNIDENTIFIED.
I DO know! Vapours.

a UFO See http://grammar.ccc.commnet.edu/grammar/abbreviations.htm (all the way to the bottom) for help determining when to use a or an before an abbreviation.
They usually see UFO's at a UFO sighting
Ufo's do exist because a Ufo is a thing in the sky that you can not explain.
movies that have UFO's in them i guess
It is unknown what is inside of a UFO.
The 'F' in UFO stands for "Flying". UFO is an acronym for Unidentified Flying Object.
The acronym "UFO" stands for "Unidentified Flying Object", not "Alien Spacecraft". UFO means you don't know what it is, which means you don't know it to be an alien spacecraft! So far, in real life, no aliens are known and proven to have come to Earth. No UFO has ever turned out to be an alien spacecraft. It's fun to pretend about such things, but taking it any further than the actual facts is like a carpenter driving nails into air-- not a lot actually gets done!
on the last level thres 1 that kills ur cars but if u were wandering if theres a cheat for driving 1 its a lie
Alien+rocket=UFO
You put the rod in the UFO and
Air +metal= ufo
If a UFO was found by a person, then it was no longer flying and no longer unidentified; therefore, no longer a UFO.
