An interesting point not emphasized in the article: each plane can require a significant amount of training time to be able to fly safely. Getting behind the controls of a $10 Million plane that you've never flown before and having to take it somewhere has got to have a higher pucker factor than the guys with guns, if you ask me.
My Brother in Law is a very seasoned pilot, so is my dad.
I asked them about this one day. Like "guys, how do you go from flying around in little Citation 5s to flying around in massive jumbo jets?"
They were confused about my question.
Why?
Because flying isn't flying, it's systems. You learn the GPS, you learn the autopilot, you learn the radio, and after that, you follow the checklist.
You're just there to press the buttons, the rest of it is planned.
They always joke that, "if you're flying IFR (instrument flight rating, meaning that every single one of your movements in controlled by the tower), you have to get clearance from control before you can scratch your balls".
I still don't believe them, but just thought I'd chime in.
