A question:

 What is the reason that airliners have engines under the wing instead
of on it?

 Possibly it will take a little bit more aluminium to construct
airliners this way, but with overwing engines the wing can deflect a
big portion of the noise for people living around airports. (This can
be reached even without improving the engines themselves!)
 The 777 is rather silent, but could be even better with engines on
the wing.
 Amsterdam Airport Schiphol has a strict noise contour now. The system
is: the less noisy aircraft are, the more aircraft can visit the
airport. So, what airlines like KLM need is: silent aircraft.
 Why are Boeing and Airbus Industrie developing the wrong airplanes
now: 737-600/700/800/900, 757-300, 767-400, 777-300, A340-500/600 and
A3XX?

 Building aircraft with engines on the wing is very well possible.
Examples are: VFW-Fokker VFW-614, Antonov An-72/74 and Boeing YC-14.

Why do airlines and aircraft manufacturers wait for ICAO's chapter 4?
Why doesn't aviation take its own responsibility?
