The U.S. Air Force was given responsibility for investigating sightings of unexplained ariel phenomenon on behalf of the U.S. Government. The investigation began unofficially in 1947 as Project Grudge. It was renamed Project Blue Book in 1952. Because many public sightings involved saucer-shaped craft, the news media liked to refer to these as Flying Saucers. However, the Air Force didn't like the term and decided to use a description that would better fit all sizes, shapes and types of objects. They referred to any unexplained ariel phenomenon as Unidentified Flying Ojects. Simply put, a UFO is anything seen in the sky that you can not immediately identify.
How about now?
In Tuesday, June 10, 2008 Metro.co.uk reported about the fighter jet hits UFO, a UFO had a mid-air collision with a fighter jet over central Europe, a leaked report has revealed. Defence chiefs are investigating claims that the Romanian MIG 21 fighter plane was struck by strange objects.
The official report says the cockpit of the jet was shattered.
Romanian defence ministry officials have ruled out all normal types of collision such as birdstrikes, ice or small meteorites. Chief investigator Commander Nicolae Grigorie said in the report: 'We can definitely say what this thing was not, but we cannot say what it was.'
The impact on a training flight above Transylvania took only 67 milliseconds and was recorded on an in-flight video camera. Pilot Marin Mitrica was slightly injured but managed to land the plane safely after the incident last year.
Baffled defence chiefs have now passed the UFO incident on to the Security Committee of European Air Forces for investigation.
