This reminds me of early days in Air Zimbabwe. Just after independence, one of our first three 'affirmative' pilots to join the airline decided to bolster his humble salary and sneak a bag of dope across to the UK for a consideration. The customs officials at LGW detected it in his baggage before it came through on the conveyor. They put a tail on him and followed him to Victoria Station and caught him in the act of handing it over and accepting cash.
He ended up in one of HM jails for six months, after which he went back to Zim and took up his previous position of FO, as if nothing had happened - protesting his innocence all along and insisting that he didn't know what was in the bag. A few years after that he was promoted to the position of 'Operations Mananger'
