Fighter jets were scrambled yesterday after unusual balloon-like objects were spotted above two European countries.
Two military planes under NATO command were deployed at around midday on Tuesday by the Romanian defence ministry in response to an object detected at an altitude of about 36,000 feet.
Picked up by radar, it was described as having "characteristics similar to a weather balloon" - but the two MiG-21 LanceR aircraft did not find anything in the area, and stayed in the vicinity for about 30 minutes before returning to base
