I have all the information I need thanks Mr.Fuji - the pilot was not IMC rated, according to my copy of CHIRPS anyway, henceforth the weather was clearly not suitable for him as on returning to the field (a short space of time after departure) he entered cloud, not just any old cloud but low cloud! The PIC was obviously not anticipating an unscheduled diversion back to the field - a bit of an elementary mistake wouldn't you say? In my copy of CHIRPS he alludes to the fact that it was a bit of a "Tally Ho" seeing as wx ahead was perfect. Big mistake. I am glad he made the report because it's a classic Human Factors case if ever I saw one, but not for the reasons intended one suspects (apart from his admitance that he should've refused ATC's instruction to land).
The PIC also says he overheard an instructor talking to another instructor and following that eavesdrop suddenly assumed the same level of competancy as those he overheard talking (one professional to another). I say a lesson in not assuming everyone has the same weather threshold and experience level as you has been learned here too - but seeing as they were instructors I'd expect that to most people this would be obvious.
VFE.
PS: It is 'mnemonic' not 'mnenmonic'.
