Glueball, et al... I won't insult your intelligence by pointing out the odds that a pilot will make it to 57 at the controls of a heavy jet, much less at a premier company with good pay.
So... at 57, you KNOW you've made it, and yes, your perspective has changed.
At 41, I figure on a 60-70% chance of making it to 57 unscathed by either FAA doctors or company MBA's. So quite frankly I'd take a bird in the hand, right now.
As the 70-year-old pilot of a Beech 18 told me when I was first starting out twenty years ago: "It's all whose ox is getting gored...."
411 - I've never asked - do you/did you own a C-411?
