IMHO, I think that to be proffessional is to also project proffesionalism.
I have an enormous respect for all that fly aircraft,but it is certainly easier to recognise a proffesional pilot by the kit they display. I was invited onto the flight deck of a 744 after a 13 hr flight to Los Angeles and could not believe how smart these guys presented after that duration. Throughout the flight the second officer made several trips to the back of the aircraft to check on someone he knew, and was always imaculate in appearance. Maybe,up front, they flew the entire trip in their underwear for all I know
..but they certainly looked like proud airman after they parked that beautiful machine and knocked off for a well earned rest.
Kudos to all of you.
Cheers
