650 - days are short and easy, pay is low

Lattitude - days are long and tough but the pay is good

Some people on the union board pretend like you need hundreds of hours of SR-71 time and at least a few Space Shuttle landings before you can touch the Challenger, but the reality is they are bitter because back when they were FOs the biggest plane they could hope for a decade was Ultra. It's basically a ****ing CRJ, if you can learn how to operate a lawnmower you'll do fine in a 650.

That is unless you show up with a wrong attitude and goof off instead of studying, then you'd wash out of 650 just as swiftly as you'd wash out of a Phenom.
