It is poor form for DJ guys to make smart a.rse comments about someone elses landing as it is equally poor form for the QF guy to "dob" in the DJ guy.
We all have a little dig every now and then about something - but it is one thing to have a joke with your offsider on the flight deck and quite another to push the PTT and transmit it to the world.
Having said that you occasionally get carried away with the moment and push the button - it however doesn't make it right.
If a DJ guy has the specifics of a transgression reported to head office - it is investigated - it is not a witch hunt - but a quiet question will be asked to see if there is any basis to the report - you would be surprised at how many vexatious reports are received - the majority made with no basis in fact - just people trying to s.hit on other people.
Sad really....
