If this really has to be discussed could we please back off the jokes, especially those that are as old as the hills.
I could understand an article about Homophobia: I just struggle to imagine why it should be airline industry specific? Are you trying to establish that it is more prevalent in this industry than in some other? Statistically, we are surely all more likely to encounter Homophobia while working as Cabin Crew than while working on a construction site, for no other reason than that there are likely to be a higher proportion of the workforce that are gay. In fact, nobody would be surprised if there were less homophobia within the airline industry than elsewhere given that we're nearly all used to it and don't really give a damn either way.
Finally, in the interest of balance, do make sure that you discuss Reverse Homophobia, sometimes known as the "Gay Mafia" which is of course an issue, although probably less so.
