No, not flight, not yet. But Solazyme—the mavericks who make their algal oil in the dark—have produced a jet fuel that passes the ASTM's standards for "aviation turbine fuel," otherwise known as jet fuel. This makes it the first such bio-kerosene from algae, being earnestly sought by the Commercial Aviation Alternative Fuels Initiative (CAAFI) and Defense Advanced Research Project Agency (better known as DARPA) as well as the U.S. Air Force.
In addition to not freezing at high altitude as biofuels are prone to do, the testing by the Southwest Research Institute shows that it has the same flashpoint, viscosity and stability as regular Jet A. Most importantly, it has the same density—a key characteristic that other alternative fuels, such as those derived from natural gas or coal, lack.

An experimental, build-it-yourself Velocity 173 RG aircraft crashed into the living room of a house in Las Vegas Friday morning shortly after takeoff from the North Las Vegas airport, killing the pilot and two people inside the home, the AP reports. The pilot and one resident of the house died at the crash site, while the other died after being taken to University Medical Center in Las Vegas. The names of the victims have not been released.
The AP reports the Velocity that crashed was certified for flight by the FAA in 2002. The Velocity—which costs between $55,000 and $150,000 depending on the kit—is constructed in sections and can be dismantled by removing about 10 bolts and some screws. The maximum width of the fuselage, without the wings attached, is 12 feet.

Researchers say that x-rays may help them predict where lightning will strike by allowing them to view what happens inside bolts as they move. University of Florida and Florida Institute of Technology engineers report in the online edition of Geophysical Research Letters that lightning zaps to the ground in 30- to 160-foot (nine- to 49-meter) stages—emitting x-rays after completing each "step." Understanding how a bolt travels, they say, is crucial in determining where it will strike. For the first time, researchers have been able to track lightning's journey using x-rays to probe its composition, much the way physicians use x-rays to peer inside the human body. Among questions they hope to answer: do lightning strikes on airplanes produce x-rays harmful to passengers?
