UFO's Over London?

So is this shit real or not?  I dunno, to me it just looks like some kinda balloon or somethin'.   I'm just not gettin' it.  I always figured if the aliens came here they'd let us know who they were.  Like if we sent a spaceship to some other planet, would we just try and sneak around and be all secret about it?  Hell no.  The first thing we did when we got to the moon was plant an American flag in its ass.  Nope, these aliens wouldn't be sneakin' around all over our planet for all these years.  They'd plant their own flag and tell us they were here to dominate the shit out of us.  It's fake.  Pay attention!
