Boeing cut the cost of making fuselages by selling a factory in Wichita to a private-equity consortium, which drastically cut costs.

ECONOMIST: The turbulent aircraft-maker tries to slow its descent

It envisions a behemoth mother ship with twin, narrow fuselages, featuring six Boeing Co. 747 engines attached to a record 385-foot wingspan, plus a smaller rocket pod nestled underneath.

There is also a feeling that some of the newer technologies, such as making fuselages lighter by building them out of carbon-composites instead of aluminium, may not yet be cost-effective for smaller aircraft.

ECONOMIST: Airbus plays the new-engine card

When people talk about reducing the energy and carbon impact of air travel, they almost always focus on improving the design of engines, wings and fuselages, or on using computer systems to shorten flight paths and eliminate delays.

WSJ: The Problem With Going Green by David Owen

While aeronautic design has come far since the advent of the passenger jet plane, making them lighter and more efficient, many designers feel that we've gone about as far as we can go with cigar-shaped fuselages and under-wing engines.

BBC: The futurist: Will green aeroplanes take off?

It hooks up hundreds of computers around the world to get them talking to one another at the same time to calculate acoustic and electromagnetic effects on the fuselages of fighter planes when they are in steep angles of attack.
