According to NASA, US airlines could save up to 250 billion dollars between 2025 and 2050. It will all be thanks to green technology pioneered by the agency and industry partners, as part of NASA's Environmentally Responsible Aviation (ERA) project.

A near-future where the skies are filled with drones carrying out deliveries and surveillance might be hard to imagine, but it is something aerospace experts are already giving careful consideration to. Improving the efficiency of these vehicles, even at the margins, could mean huge energy savings and more reliable services across the board. To this end, Australian researchers have developed a fixed-wing aircraft that uses natural updrafts to climb higher, inspired by the ability of the kestrel falcon to hover while searching for prey on the ground.
If a recently-announced consortium of scientists and aviation companies is successful, you could one day be flying in jets powered by the remains of decay – otherwise known as biofuel from forest-industry waste. The project will be led by the University of British Columbia (UBC) and NORAM Engineering and Constructors, and includes aviation and related companies Boeing, Air Canada, WestJet, SkyNRG and Bombardier.
Small Unmanned Aerial Vehicles (UAVs), or drones, have quickly gained popularity with the public. And as is so often the case with rapidly advancing technologies, it can be hard for the public to know legally what they can and can't do with the technology – or in the case of drones, where they can and can't fly. To help dispel confusion surrounding drone flights, the US FAA is beta testing its B4UFLY smartphone app, which tells users about any restrictions on unmanned aircraft they might want to fly in a particular area.
The Solar Impulse team has announced that the completion of its
round-the-world solar flight will now be postponed until next April. The
batteries of the Solar Impulse 2 solar-powered aircraft sustained
damage as the aircraft ascended to an optimal energy-management
altitude of 28,000 ft (8,534 m) on the first day of its
ambitious Japan-to-Hawaii flight. It
is believed that a high rate of climb coupled with over-insulation of
the gondolas resulted in irreversible overheating damage to the aircraft's
