I've been on the UK Airprox Board ... well not on it
, but dippng into their published reports ...

Fascinating language some of it ... e.g. one report involving a couple of Airbuses:
'All other things being equal, Members considered that best practice is to reduce the v/s to a much lower rate to reduce the chances of TCAS and STCA generating alerts'
'Both ac had been cleared to separated levels which had been correctly read back, therefore there are no ATC errors disclosed'
So, for Mission Impossible fans, if I read that correctly, your mission, should you choose to accept it and read it back, is to stick to what you are told and be careful not to upset the movement detectors, and a quiet life with a mission completed is your reward?
