I agree with the ancient greek...
Real pilots can normally conduct flights in this region normally...
However, most Real pilots having never been exposed to this type of flying, would choke on their first check out...
My hat is off to these guys/gals...Of course they would rather be "Mainline" at a Major Carrier...OR MAYBE NOT!
Any Real pilot who has been confronted with the conditions these pilots encounter on a daily basis...most likely couldn't handle flying under these conditions...
I'd like to give it a go, but every day?
The heart would give out before your medical...
My hat is off to them...DI3G....
