For more than 20 years, the 757 provided value to airlines and travelers around the world. The 757, along with the 767, which was developed during the same period, introduced many technological advances in aviation. The 757 was the first airplane to use a new wing design and high-bypass-ratio engines that helped create one of the most fuel-efficient, clean and quiet airplanes -- even by today's standards. On Oct. 28, Boeing marked the completion of its 757 commercial airplane program.
