" Now that we think the captain was legal in Mexico, how about the 20 year old FO? I was flying J3 cubs and cessna 150's when I was 20. This kid is flying right seat in a Lear Jet? What training did he have?"
Just my 2 cents worth....I met a Falcon 10 FO during my first night long distance cross country flight. He started with a Texas (?? it was awhile ago now) as basically a janitor. Became an FO at 21 on his birthday and at age 24 had accumulatd quite a bit of time when I met him. (BEAUTIFUL aircraft btw). I believe it's entirely what you do with your time that matters. You could go to one of the best training centers, screw off and just barely make it through....OR, go to a lower reputation center and bust your hump. I KNOW which pilot I would want...!!
