Experts Re-Create Nazi 'Stealth' Fighter to Test Tech

The last remaining Horten 2-29, a Nazi fighter plane from World War II, is stored in a U.S. government warehouse akin to the one at the end of 'Indiana Jones and the Raiders of the Lost Ark.' With a mostly pressed-wood body and a sleek all-wing design, it looks like something created in Hollywood, too. But this aircraft isn't just a pretty piece of painted plywood. It very well could have changed the course of the war.

A group of experts from Northrop Grunman, a global security company, recently re-built the Horten 2-29 for a television special airing Sunday on the National Geographic Channel. The team's goal was to determine if the rumors were true; was the Horten 2-29 the world's first stealth fighter? They tested the original aircraft with WWII-era radar technology before building a model held together with primarily wood and glue. Then, they hoisted it on top of a five-story column and subjected the model to the same radar technology.

Virgin Atlantic Flies World's First Biofuel Flight




Sir Richard Branson is liking the color green: His Virgin Atlantic flew the world's commercial aircraft flight powered with biofuel on Sunday, demonstrating how it produces less carbon dioxide than normal jet fuels.

"This breakthrough will help Virgin Atlantic to fly its planes using clean fuel sooner than expected," said Virgin's president, Branson, before his Boeing 747 flew from London's Heathrow Airport to Amsterdam's Schiphol Airport.

While the flight drew praise from many who saw it as a useful experiment, others called it a publicity stunt and doubted the quantifiable long-term benefits of biofuel.

"It's great that somebody like Richard is willing to put some of his billions into an experiment aimed at reducing the climate change impact of aviation," said James Halstead, an airline analyst at the London stockbroker Dawnay Day Lochart. "But there are a lot of unanswered questions about the usefulness of biofuels in the battle against global warming."

The flight was partially fueled with "a biofuel mixture of coconut and babassu oil" in one of its four main fuel tanks which, frankly, sounds delicious.

Is Boeing's New Dreamliner Hackable?

Is Boeing's New Dreamliner Hackable?

Boeing's new 787 may look like most other commercial airliners on the outside, but under the paint, it's a technological marvel. In terms of construction, the thing is lightweight and so more fuel efficient than its predecessors. But the really impressive bits are the computerized ones that keep the thing in the air and pointed in the right direction. The craft has an integrated computer system that can automatically contact Boeing systems and report issues via an airborne Internet connection. This integration, however, has raised some security fears among many experts, resulting in the FAA threatening to ground the plane unless Boeing proves that the ship is hack-proof.

The primary problem in the eyes of the FAA is that the connection that the aircraft uses to talk to the ground is the same that will be used by passengers to provide in-flight wireless Internet access. The fear is that passengers on-board the plane could somehow hack into the 787's control systems and cause the ship to crash.

Boeing is saying that these fears are unfounded, and that the two networks, though connected, are secure. That said, Boeing is planning on adding additional layers of security like firewalls and network hardware and software that restricts the flow of data from one network to another. In development since 2004, the 787 is scheduled to hit the air in November of this year, so Boeing doesn't have that much time to figure it out, and it'd be a real shame if the thing couldn't get airborne not due to a aerodynamic design flaw, but rather because of a security flaw.

In-Flight Cell-Phones a Go In Europe



While the FCC and FAA hold in-flight calling and texting at bay here in the US, the European Aviation Safety Agency is on the march to rid the world of this one last bastion of cell-phone-free space, at least in the E.U.. Ryanair, Qantas, and Air France have been testing in-flight mobile use for the past several months. The results of the trial have been impressive enough for the EASA agency to give approval to Airbus' OnAir service, which will be used by Ryanair and Qantas on flights this year.

Good news for those who would rather keep airplanes cell-phone-free: The flight crew will maintain control over the system, which means they can shut off voice channels when, say, it's time for everyone to sleep, while still leaving text-messaging and data capability intact. The service will roll out initially in short haul flights in Western Europe, though Airbus has stated its intent to take the program global, if it can win approval elsewhere.
