Boeing 737 MAX aircraft completed its first flight on Friday, taking off and conducting tests for about three hours before landing safely at Boeing Field in Seattle.
The smooth flight of the new aircraft marks another step toward scheduled delivery to airlines in 2017.
The plane is the fourth version of the original 737, which made its first flight in 1967 and has become one of Boeing's most profitable aircraft.
Boeing has sold 3,072 of the planes and is racing to sell more as it battles for market share against rival Airbus's competing A320neo, which earlier this month was delivered to its first customer, Lufthansa.
Boeing is expected to deliver its first 737 MAX to customers in 2017.
At Sismo Soluciones we have started the initial jobs that will lead to a new development of the 737MAX cockpit. It´s a long term development but it will keep Sismo Soluciones in the forefront of the simulation industry.
