Boeing's much-anticipated 737 MAX is scheduled to take its first flight Friday, between 9 and 10 a.m. PT.
For the unveiling, Boeing is live streaming the event.
The plane is scheduled to take off from Renton Municiple Airport in Washington — where the 737s are made — and make a 90-minute flight to Boeing Field, just south of Seattle.
The 737 MAX is a single-aisle plane that is 20% more fuel efficient than current 737s, because of its split winglet design.
