A video of an Unidentified Flying Object (UFO), sighted in the last week of January, is doing the rounds of the Internet. The footage, uploaded by Pisosmadera, shows eight objects flying in formation in skies above Mexico.

Do Aliens and UFOs Exist?

The objects appear to hover for periods of time and move as if controlled by a collective intelligence. At a quick glance, given their shape and colour, it is possible to mistake them for birds. A closer look, however, will confirm they are not birds.

However, before UFO enthusiasts get too excited, it is possible these may be nothing more than human-built aircraft or drones being tested. Scott C Waring, of the Web site UFO Sightings Daily, speculates:

"At first glance I made the mistake of assuming this was a video of seagulls. I was mistaken. Not a single one of them flap like a bird would. These objects appear to be a fleet of UFOs or even possibly DARPA drones being tested in Mexico. Notice how the UFOs or drones synchronise in flight and clearly show that they are controlled by intelligence. They also look a little like the secret aircraft the TR3B."

Meanwhile, a video of a fast-moving UFO was taken on 1 February, aboard a commercial aircraft in American skies. The video shows an object flying past a window, at considerable speed, and there is this comment heard in the background: "Whoa, did you see that?"

The video has been posted on YouTube by JoinOurBandOfBelief, with this comment: "This footage was just sent to us last night [Feb. 1] and was shot while on a flight to Massachusetts Jan 2013. Thank you for this great video."
