FIGHTER pilots were put on red alert in a UFO drama over Germany, it emerged yesterday.

Air traffic controllers tracked a mystery object speeding across the entire country.

Investigators have checked and excluded conventional aircraft, weather balloons and freak atmospheric conditions.

Axel Raab of Germany’s air traffic safety office, the DFS, said: “We have ruled out all the conventional possibilities — it is a mystery.”

There were dozens of reports of the object as it flew across southern Germany on January 19.

It vanished above an area used by US troops on training exercises.

Mr Raab said: “It confused radar operators because it kept flicking on and off the screen. Then it simply vanished.”
