Yellow Sun..I think you may have misinterpreted my reply!
I was not referring generally to police-officers (former and current) who may, or may not, have flying experience. I was referring expressly to those former police-officers employed by the CAA for investigative and interview purposes.
My reply was based on 2 personal friends/acqaintances currently/formerly doing that exact same job and recent stories in 2 UK flying mags.
I was merely trying to offer constructive advice based on facts and personal experience.... Cheers, BM
