flying overseas introduced me to things that I would most likely have to be a 10 year legacy 777 FO to experience.. Screaming into an HF radio over remote areas, weighing options for a medical diversion over central Africa, plotting escape routes over desolate western China, ETOPS, the baffling ATC of the Indian subcontinent, metric altitudes and heavy accents in Russia and other CIS, flying a freighter version with associated cargo ops, plus flying and working with dozens of nationalities and personalities I wouldn't have otherwise been exposed to.
Does all this make me a better/more competent pilot? Not saying that at all...
