Noise around an airport *is* a problem, but I don't believe this is a
valid argument. 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.
