The big deal is that it is a twin engine aircraft that flew so long and so far. There are different flight rules for twin and four-engine aircraft, such as twins must stay within a certain distance, en route, to an emergency landing site should an engine fail. This is a push to qualify the cheaper to buy, and less costly to operate, twins to fly the four engine routes.
