Boeing 737 Max, Involved In 2 Crashes, Is Fastest-Selling Plane In Company's History

The Boeing 737 Max is the fastest-selling plane in the company's history. And now it's under immense global scrutiny after the plane has been involved in two deadly crashes soon after takeoff in less than five months.

Boeing has pinned high hopes on the 737 Max. "We expect 737 Max to account for approximately 90 percent of total 737 deliveries in 2019," the company's chief financial officer, Gregory Smith, said in January. "In all, [Boeing] is expected to deliver between 895 and 905 airplanes for the full year."

So far, the manufacturer says it has received more than 5,000 orders for the fuel-efficient plane from more than 100 customers worldwide. The 737 Max has been key to its competition with top rival Airbus, which has found success with a similar model.
