Tankertrashnav.
Like you I know nowt about the Chopper world but I do know about standards of supervision and airmanship having done two staneval tours and scruffy tankerw.....s they may have been but they were and I hope still are more professional than many of the more shiny elements of the RAF. There can be no substitute for strong supervision and independent checking, it is not that it is too expensive to provide, it is too expensive not to provide.
