Bad timing and dangerous after the recent disappearence of MH 370. Not in the heart of the busy European air space, electronic military exercises were to blame for the mysterious disappearance of dozens of planes from air-traffic control screens.

About 50 planes temporarily disappeared from radars in Austria, Germany, the Czech Republic, and Slovakia between June 5 and June 10, Austria’s flight safety monitor said.

German and Czech air traffic control also reported brief disappearances.

Slovakia blamed the outages on planned military exercises.

The disappearance of objects on radar screens was connected with a planned military exercise which took place in various parts of Europe…whose goal was the interruption of radio communication frequencies. This statement was made by the Slovak air traffic services.

Right after the problem with the radars was detected, the organizing party was made aware and the exercises were stopped, Slovakia’s air traffic services added.

Slovakia did not mention a military force involved in the exercises, but Austrian media pointed towards NATO.

Austrian daily Kurier reported on June 7 that the first disappearance problems coincided with NATO conducting electronic warfare exercises in Hungary.

During the exercises NATO was reportedly using devices that can interfere with enemy radar, according to the Telegraph.

German air traffic control stated that it is trying to identify the cause of the outages.

Authorities said the outages did not pose any serious threat.
