That article in the OP is nothing more than sensationalistic BS. I love the "industry expert" that they quote, who has never spent a minute of time working in the airline industry. I'm betting that he got turned down by the majors....
I have been in the airline business for almost 30 years, and other than the few widely publicized events, many of which end up being BS, I have never seen, or even heard about, one of my co workers showing up for work under the influence. Ever.
I knew ONE guy back in the '80's with a cocaine problem, and he didn't last long in the industry, even after rehab. And that was long before the mandatory drug testing days.
As for Fox "news".....
Why are pilots so fascinated with it? It must be a contractual thing, because every single one of my airline's crew lounge TVs are tuned to Fox News 24-7. The old TV in my base lounge had the Fox logo so burned into the lower corner of the screen, that you could almost see it with the TV off. If I am there by myself, I either turn the channel to something more entertaining, or just turn off the TV and hide the remote. I had an unscheduled, 4 hour sit in another domicile last month, so I put the TV on CNBC, hid the remote in a drawer, put my headphones on and enjoyed the "show". It was like watching addicts jonesing for a fix...... Sorry, but I can only take so much of the Megyn Kelly leg humping.
Oh, and it's not a political thing with me...... What sane person wants to watch ANY news 24-7?
