were scrambled after the service’s surveillance system
detected an aerial object that looked like a weather balloon
flying in the Romania’s airspace,
the Romanian defence ministry said on Feb. 14, 2023, according to Reuters.
The two interceptors flew towards an area located in southeast Romania
around 10 minutes after the suspicious object was first detected but once there,
they could not confirm the presence of the balloon,
reportedly flying at an altitude of 11,000 metres.
The aircraft patrolled the area for about 30 minutes, before returning home.
