Offshore - Don't fall into this wind up mate - you're too decent a chap to be publicly swiped at by this person. He/she is obviously not what they say they are (certainly NOT management) and they do this to let off steam against an industry which has probably damaged them or their aspirations some time in the past.
I would hazard a guess that they failed as a pilot sometime in their weak past and now find this forum as a relief vent for their anger/ frustration.
The best way round this ignominious detritus is to ignore it....
Can't you see - this type of person is a figment of his own imagination
Let's all move on....perhaps he won't follow?
