Is false flag UFO alien invasion planned for London Olympics?

The BBC is planning a documentary dealing with a variety of conspiracy theories including UFOs and aliens appearing at the upcoming London Olympics. According to Paul Joseph Watson of Infowars.com, the UFO alien invasion meme was being promoted in the upcoming BBC documentary to discredit the burgeoning 9/11 and 7/7 truth movements. There are other perspectives warning that officially sanctioned media events such as the BBC documentary act as triggers for false flag events to go forward. Both 9/11 and 7/7 are described as false flag events that were foreshadowed by television shows and mock terrorist simulations. So is the upcoming BBC documentary discussing a possible UFO alien appearance at the London Olympics part of a planned false flag alien invasion?
