6-10 months after any sort of economic recovery (airlines lag other industries), and then factor in the point where the effects of age 65 start wearing off...those two variables are complete unknowns...I'm banking on 2012, b/c it's been said it will be the end of the world before there is a pilot shortage, and well, you know, all those people say the world is coming to an end in 2012...so you'll see a huge boom in pilot hiring and attrition right before the world comes to an end...
At least I'll have marketable skills in hades...because, you know, it's evil to make people ride in RJs, so I'm sure there are lots of them down there...
