UFO over London, England

UFO from outer space seems to exist, as shown in this footage, but scientists still do not have a reliable explanation.
These three lights flew about 5 minutes south west of London, England on 05/02/2012 / 02.05.2012. Twenty-six people have reported this celestial phenomenon.

Lights arranged in a triangle as a sign that you are on the trail of aliens

The video looks as if two objects disappear, and the third at high speed away in an unknown direction.
For now, all who testified about this event and feel overwhelmed by the impression that it is something alien because they have no other explanation.
Experts did not offered a reasonable explanation, so for now there is no official version of the story.
