I accept both the technical answer and (some of!) the practical ones - I have trained and worked alongside current and ex-service ATCOs. My point, I guess, is should we consider it right and proper that someone with experience of, for example, operating at multiple airfields with large variations in traffic types and mixes should have to start 'from scratch' to get a job once they leave Her Majesty's service? Should we not advocate at the very least some sort of fast track/streamlined course?
