So far this year the NBS has reported already 30 incidents altogether where Russian military units, whether ships or planes, have strayed close enough to Latvian territorial waters and airspace to warrant their identification and observation.
The Russian air force planes in particular rarely, if ever, use their transponders in flight, causing concern among military and civil aviation authorities alike about the hazard to passenger planes unaware of their presence.
