"I've been here through seven models, from the -200s all the way up to the current model," said Thomas Hadley, 737 Interiors manager. "Amazing. Simply amazing. I had no idea that it would ever reach to that point."

. The MAX, currently in development, is the future of the 737 program, and . United's order also included 50 737-900ERs.
