New airliners are built using the latest technology in composites and turbofan engines. Composites are stronger and lighter than alloys used today, and contribute to fuel economy by *reducing* weight. Also- new, more efficient turbofan engines are used for fuel economy as well. These turbofan engines are not only efficient, but *quieter* than turbojets. I attended a school located on a good size regional airport, and the new 757's that flew in were quieter than any of the other jets. Jim Nesheim :-)
