At an airline that I worked at some years ago we had what were called ' permanent F/Os'.
Not a term that I particularly liked, but it referred to F/Os who were unable to upgrade to Captain status due to some inability on their part to make the transition from the RHS to the LHS.
Lambourne is obviously in this category and I sympathize with the situation he finds himself in.
However, presenting as a bitter and twisted disgruntled F/O achieves nothing for him other than pity and sympathy plus a lot of anger from the Captains who have to pull him into line to operate to a suitable standard. It probably means also that he wont be given a second chance to upgrade to command.
Hopefully, Lambourne will moderate his attitude so that one day he may truly be a member of what we proudly call the "Profession of Airline Pilots "
