The contribution of aircraft to greenhouse gas emissions has been well documented and while biofuels are being trialled in an effort to combat the issue, an expected doubling in air traffic by 2035 suggests that a fundamental shift in technology is needed to make real progress. That's the starting point for the D “double bubble” – a design concept presented to NASA by an MIT led research team which promises a 70 percent improvement in fuel economy, reduced noise, lower nitrogen oxide (NOx) emissions and the ability to use shorter runways.
