...not entirely comfortable with 3000hrs being sufficient for a jet command.
Jet, Turboprop, Piston Single, Glider - It doesn't matter. What counts is the selection, training and thinking of the crews.
...the mess that was the MAD-VLC mass diversion.
Was due to the weather. More fuel would have enabled them hold for longer, with no guarantee of a better outcome. And although I can not stand RYR, I do rate their pilots. They are some of the best in the industry. Also, whenever there are mass diversions I've learned that a yellow streak is a good thing to have. Beat the rush, nick the best parking spots, get fueled, get the buses etc.
