A total of 13 aircraft suddenly vanished off radars for about 25 minutes on two occasions over Austria and neighboring countries, Austria's flight safety monitor said, calling for an EU probe into the “unprecedented” incidents.
The flights vanished from air traffic controllers’ screens in Austria on June 5 and June 10 for 25 minutes each time, Marcus Pohanka of Austro Control – Austria’s flight safety organization – said Thursday.
Air traffic control in neighboring regions of Germany and the Czech Republic also reported similar problems.
Pohanka said the location, height, and identity of the 13 aircraft vanished over Austria both times, in what he called “unprecedented” incidents, AP reported.
He added that some neighboring countries had experienced similar problems. The daily Kurier, based in Vienna, elaborated that similar problems were experienced by flight controllers in Munich and Karlsruhe in Germany and in Prague, Czech Republic.
The Kurier cited an unnamed expert as saying that the problem was most likely to do with interference between the aircraft transponders and the ground.
Excitement around Nato-sturgeon transmitter
Also the Austro Control supposes Nato manoeuvre as a cause for disturbed air traffic control.
Now after the failure of the civil air traffic control systems the last Thursday rules big excitement. Conspiracy theorists suppose an electronic poster of the Americans as a cause. And at the authorities one tries to kalmieren.
Like him CURE reported, the airplanes of the screens of the Austro Control disappeared Thursday from 14 o'clock. Some appeared again to disappear once more. Obvious the Transponder of the jets had fallen out by the dozen. Those data transmitters which transmit the Austro Control flight altitude, course and speed. This signified a burned situation for the flight pilots. Since they have to guarantee a free from problems expiry of about 4000 overflights over Austria.
The Austro Control switched over to manual operation. Additional flight pilots were used and other airspaces were opened as well as the safe distances were increased. The positions of the airmen were questioned on speech radio. Thus the system failure could be got over without collision.
At the same time the air traffic control headquarters were also concerned in Karlsruhe, Prague and Bratislava.
The COURIER could bring in experience that precisely at this time in Hungary a Nato practise took place for electronic fight guidance (EloKa). Practise purpose was to block the Transponder of airplanes with sturgeon transmitters. Besides, a mistake might be passed, and the sturgeon signal spread over half Europe.
Austro Control speaker Markus Pohanka divides the suspicion that a workplace accident has been the cause in NATO also. Compared with the APA he explained: ' Cause for the failure a Nato practise could have been in Hungary. ' Otherwise the Austro Control speaker tries to kalmieren. The failure has lasted only 25 minutes. According to the information, to him CURE are, it lasted in Austria till 17 o'clock and in the neighboring countries till 19.30 o'clock.
NATO delivers in such cases usually no statement. Probably, however, the announcement released different conspiracy theories. Thus possibly one courier's poster supposed that the Americans disturbed the radar to bring illegally an airplane through Europe. However, this is no logical theory. Since in this case they would have had to disturb the radar system of the federal army. Since the army with his active system 'golden bonnet' sees in contrast to Austro Control also those airplanes which have switched on no Transponder. Most highly Michael Bauer, speaker of the ministry of defense, sticks to the fact that the military radar has gone on working all the time freely of disturbance.
A similar incident is reported from the USA. There the flight schedule of an US-American spy airplane U-2 had wrong been interpreted on the 30th April by the computer of the aerial traffic check Los Angeles. Indeed, U-2 flew by extreme height. However, the computer arranged them in normal flight altitude. More than 200 flights were thereby delayed or had to be stroked generally. Other dozen were moved to smaller airports.
Indeed, this incident has another cause than the incidents of Thursday, but the effect was the same one. Also the US-flight pilots changed on 'manual operation'. They had to reach to her phones and radio devices, and question on the topical flight schedules and on positions individually.
