QQQ, in the last 2 years I have personally been involved in 17 formal investigations regarding significant unauthorised/inadvertant penetration of Class A CAS. This has involved lengthy radio tape transcripts, impounding of radar tapes, statements from all concerned and thorough investigation. Only once was an individual subject to "punitive" treatment (£2000 fine) as, despite all this evidence, he swore blind that he had not penetrated CAS. In every other circumstance, the Authority and the individuals concerned agreed about the cause of the error and identified apprpriate lessons.
Believe me - I have not been dreaming.
