Historically, you've needed to be a military officer (O-6 or above, supposedly) but they're probably having a hard time finding guys at that level these days who are willing to do it.
O6 or above? With 737 experience? That sure narrows the pool. The retired O6's I know are pretty much done with flying for money. If they do it at all it's for fun and I doubt flying a commuter bus between area 51 and LV is defined as fun by many people.
I think it would get boring fast. I envision hours of sitting in a building with no windows at area 51 with no cell service or internet waiting for workers to end their shifts. But at least you could say you were at area 51. Never mind.....I guess you couldn't.
We started layoffs at my work (RIF). Its on the news. Maybe I should start looking somewhere and have a plan? I have 18 years.
