MOD Policy on Unidentified Flying Objects (UFO)

The document states that the MOD has no expertise or role in respect of 'UFO/flying saucer' matters or the existence or otherwise of extraterrestrial lifeforms, remaining open-minded on the topic. To date, the MOD knows of no evidence which substantiates the existence of these alleged phenomena. Reports are examined solely to establish whether they might indicate a breach of UK airspace by hostile or unauthorised air activity that could present a defence threat. No such evidence has ever been found in any UFO report. The MOD does not attempt to identify the precise nature of sightings and believes rational explanations such as aircraft lights or natural phenomena could usually be found, but it is not an appropriate use of defence resources to provide an aerial identification service. Members of the public are directed to civilian organisations if they wish to pursue identification.
