After radar air traffic control systems were paralyzed in parts of Central Europe by an unknown jammer last Thursday, on Tuesday planes again
disappeared from the screens of air traffic controllers. During the first incident, a NATO exercise had been suspected to be the reason,but at the
time of the second incident there had been no NATO exercise. The European air traffic control Euro Control and the European Aviation Safety Agency
(EASA) have initiated investigations.
In the first blackout in the previous week , from 14 o clock on planes disappeared from the radar screens of air traffic control centers in Vienna,
Bratislava, Karlsruhe and Prague, even though the aircraft were in the air. Something unknown had obviously disturbed the transponders of the flights
who provide the ground stations identity and flight details. This can have dramatic consequences. Because up to 4000 machines per day traverse the
Austrian airspace alone. 50 flights may be in the air over Austria at any given time.
The fact that there was no crash is due to a well thought out emergency program by air traffic controllers The Austro Control immediately increased
the staff on duty. Additional air spaces were created to increase the safety margins of the airplanes. The pilots gave their positions by radio and
were held by the air traffic controllers on track. The error affected only the civilian systems. The military radar - even that of the Armed Forces -
After four air traffic control centers were affected at the same time, the trigger had probably come from outside. A suspect was identified quickly.
In Hungary, NATO exercised its electronic warfare against transponder aircraft. So the researchers assumed that overzealous Electronics Warriors had
the interference not only directed against a practice target, but also mistakenly irradiated half of Europe.
On Tuesday a second blackout followed. Between 13:30 and 15 clock suddenly planes disappeared from the screens. This time the air traffic control in
Vienna, Munich, Karlsruhe and Prague were affected.
The location National Operations Centre was contacted in Uedem in Germany as they did in the first incident. This position command center had
suggested the NATO exercise for electronic warfare in Hungary in the first case as a possible cause. But this time the experts disagreed. The exercise
in Hungary was over. And a current ongoing exercise in southern Italy is not technically able to disrupt radar systems to Northern Germany.
If it was not NATO, then who is? In intelligence circles they speculate about two possibilities: Such a large-scale disturbance could take place only
via satellite. Only the U.S., Russia, China and India would be capable of doing this. What interests should they have to make such troubles? Or did
terrorist hackers succeed to penetrate the ground-based data traffic of the air traffic control?
Austro Control spokesman Markus Pohanka also confirmed the second incident. This time it didn't result in so many outages as a week ago. Planes at
high altitude aircraft had been affected. Pohanka tried to calm things down: There was no danger. The incidents would rather have shown that the air
traffic controllers are in a position to securely manage the airspace even when there are system outages.
