As the MoD releases 7,000 pages of information on successive governments’ UFO policies, Parliamentary questions, public correspondence and sightings of UFOs, we take a look at what people see when they spot UFOs.

The National UFO Reporting Center database of UFO sightings contains more than 60,000 UFO sightings, with descriptions including the shape, location and duration of the sighting.
People most commonly see a light, circles, spheres and an oval when they witness unidentified flying objects, with the most common shape reported to be a triangle.
Many of the sightings are located near cities and heavily populated areas, as shown in map below which plots all the sightings across the world.
The vast majority are in the western world, concentrated in the USA, with nearly no sightings in the continent of Africa outside of South Africa.

The latest batch of files on UFOs from the MoD show that:
• Tony Blair was briefed on UFO and alien defence policy as he was so concerned about the disclosure of classified information on extra-terrestrials when he was Prime Minister
• A Whitehall civil servant was paid to investigate UFO reports
• Government officials believed aliens ‘might come here for holidays’ and suggested harnessing UFO technology for British defences.
