Karel_x,
At 10:39:50 gived ATC distance 6 km. Acoustic signal of OM sounded betveen 50-58th second, middle is 10:39:54 and distance OM-THR is 6.26 km. The horn of OM sounded 4sec after moment when ATCO was reporting 6km. It ought to sound 3.3sec earlier.
Huh? Are you saying that because of the radar malfunction, the controller didn't know where the LOM was, and it was a sheer coincidence that he reported the airplane's approaching the LOM exactly when the airplane was approaching the LOM?
