Sing a poor  

they are as well trained as US pilots?

When you start off with a language barrier right out the gates .....you are already at a disadvantage.

sure there are a few pilots who can fly well from foregin countries.  Many of them fly for us here at my Company.....but I can tell you they still write up dumb $#!t.

I'll take a US english first language, good ole boy born and raised in the US pilot over a top gun ace foregin pilot any day of the week to fly my bird.  Because I know he knows what the hell is going on and the limitations of the aircraft.
