'BAA invented ‘green’ jumbo to help win Heathrow case'

"BAA, the operator of Heathrow, used the low emissions figures of a
non-existent green jumbo to help clinch the environmental case for a
third runway.

The twin-engine 450-seat “virtual” jet was invented for the
environmental modelling required in the government consultation after
BAA realised it would otherwise exceed the limit for noise and
pollution.

According to BAA submissions, the green jumbo will account for more
flights out of Heathrow by 2030 than four-engined giants such as the
double-decker A380, or the new generation of Boeing 747s. It promises
to be the world’s quietest and cleanest jumbo.

There is just one snag: Airbus and Boeing, the world’s biggest
aircraft makers, have no intention of building it.

“Nothing like this is on the drawing board,” said one senior industry
source. “I don’t think it’s feasible because the size of engines that
would be required for this plane to safely take off don’t exist and
aren’t under development.”    ....
