It came through quietly, but boldly. The Boeing Company’s much-touted 787 Dreamline cruised into Denver International Airport on Tuesday to test its highly advanced systems, making three landings and takeoffs, notes The Denver Post. It’s presumably a positive step for Boeing, considering that in November tests were halted following a fire aboard a flight over Texas. Boeing says 787s will be 20 percent more fuel-efficient than similar planes and produce 20 percent fewer emissions.

The tests could be a prelude to the arrival of Japan All Nippon Airways at DIA and nonstop flights from the airport to Tokyo. “ANA is still saying Denver is one of the top markets,” says DIA communications and marketing chief Sally Covington of the possibility of such flights. Meanwhile, a big hurdle to the 787’s success—certification in Europe—appears imminent this year, reports Bloomberg News.
