Listening Watch
Please, please,please, at this sensitive time ensure that you have your radios turned up to an appropriate volume, and if you don't hear ATC for a while ask yourselves "why"??
I believe that London today had 2 aircraft go significant distances through the airspace,in the cruise without answering to ATC.
One was a US carrier and the other from a former Yugoslav republic,either of which could have been a potential target.
