Boeing Co's 737 MAX aircraft completed its first flight on January 29, 2016, taking off from rain-slick tarmac and conducting tests for about three hours before landing safely at Boeing Field in Seattle.

The 737 MAX, featuring new engines from CFM International, 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 is expected to deliver its first 737 MAX to customers in 2017. Southwest Airlines Co is scheduled to be the first airline to add the 737 MAX to its fleet.

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.

Let's take a look at the four-minute time-lapse video showing just how quickly Boeing put the first 737 MAX together.
