Germanwings A319 near LSZB, loss of separation

[Ruputer]

After Uberlingen a happy goal for Skyguide:
"A Germanwings Airbus A319-100, registration D-AKNK performing flight 4U-2529 from Barcelona,SP (Spain) to Stuttgart (Germany), was in contact with Zurich (Switzerland) Center descending from FL340 through about FL260 about 6nm northwest of Bern Airport (Switzerland), when the crew reacted to a TCAS resolution advisory and climbed to FL272."

Another Feed!
BTW: Someone could explain the "blank out"-option for silence in Audacity?

Sorry for my english, I'm not a native nor living in an english-speaking-country so far.

Great catch!

The Swiss controller argued they were only cleared down to FL280 - not FL250. Couldn't spot the original clearance. But at 0:57 into the first recording, you can clearly hear German Wings: "2529er decending FL 2-5-0". There is no objection from the controller at this point - she just asks about their current heading and continues. 2min later there's the TCAS RA...
At first glance, controller doesn't look too great here. But will be interesting to hear from the investigation. Hurray for TCAS...
