And by the way: there were few other traffic on same frequency, and had conversations at black boxes.
True, but they don't contain conversations ATC controllers and different units (Kiev, Lviv, Dipno) are having among themselves.
Scripts are saved in WAV format, and can't be technically confiscated: as they are stored on different servers at ATC facility and UkSatse main office.
Oh please, come on. Any 10 year old can convert .wav to .mp3 or make a copy.
Why can't these ATC tapes (.wav if you will) be made public, just like that alleged intercepted phone conversation between the separatists?
