• How many times since 1" January 200 I have unidentified aircraft or .'flying objects' been
detected approaching andior entering United Kingdom airspace by air defence radar?
Since I January 2001 fifteen aircraft remained unidentified as they were detected approaching UK
airspace by the air defence system.
2. How many of these aircraft or 'UFOs' have been subsequently identified and found to be
harmless?
Subsequently, nine of the aircraft were positively identified.
3. How many, if any, have been identified and found to be aircraft of a potentially hostile
foreign power?
None were found to be unauthorised incursions by aircraft of a potentially hostile foreign power.
However, it should be noted that there are occasional, pre-notified and authorised movements of
civil and military aircraft from potentially hostile nations into UK airspace.
4. How many, ij·any, have remained unidentified?
Of the six tracks that remained unidentified, two never actually entered UK airspace and the
remaining four were assumed friendly based on behavioural patterns.
I hope this is helpful.
Yours sincerely,
