I've just bunged some links here to some vids that are clearly NOT UFOs.
Just in case anyone needs a comparison/reference point, for things that they can't identify.
#1. Plane coming in to land at night.
Not obvious to start with, but as it gets closer, well, you decide.
http://www.youtube.com/watch?v=IBJ32eVWVNc
#2. Plane high in sky during daytime.
Again, not immediately obvious, but as the footage continues it becomes much clearer.
http://www.youtube.com/watch?v=NN0IixsWh1U
#3. Remote control saucer shaped model aircraft.
(zip forward to 3:02 to see flight of 'geobat')
http://www.youtube.com/watch?v=WKiQqORDnJQ
#4. Remote control model with a more 'traditional' UFO shape.
http://www.youtube.com/watch?v=sdGVI7kJld0&feature=related
#5. Experimental 'rotating wing' remote control craft.
Very odd flight characteristics.
http://www.youtube.com/watch?v=5ChvTm8peuo
#6. Ascent, separation, and re-entry of the Ares I-X rocket.
As filmed by observers from a distance.
http://www.youtube.com/watch?v=D8NuBAjXKKQ
#7. Helicopter at night with searchlight - most likely police.

#8. A collection of 'chinese lanterns'.
