Though a month of investigating the grounded Boeing Co. Dreamliner 787 passenger jet and its fire-prone batteries has turned up clues, federal officials reported that the cause of the problem remains a mystery. Meanwhile, airlines have made other arrangements for passengers for the foreseeable future as its 787s are grounded and the battery issue is investigated. Speaking to reporters Thursday from Washington, National Transportation Safety Board Chairwoman Deborah Hersman said investigators found a short-circuit in a lithium-ion battery on one aircraft and even traced it to a specific cell, but they didn't yet determine the root cause.

MOJAVE -- The test flight appeared to be going well when the 12-foot rocket soared into blue sky. But upon its descent, something went wrong. On Tuesday, Masten Space System's Xaero test rocket exploded during a test flight here at Mojave Air and Space Port. There were no injuries, but the vehicle was lost. The 2-year-old vertical takeoff and landing vehicle launched around 10:30 a.m. on its most ambitious mission to date. It hit 3,280 feet and slowly came down for a landing under rocket power when it began wildly oscillating.

The results are in from last summer's attempt to test new technology that would provide the Pentagon with a lightning-fast vehicle, capable of delivering a military strike anywhere in the world in less than an hour. In August the Pentagon's research arm, known as the Defense Advanced Research Projects Agency, or DARPA, carried out a test flight of an experimental aircraft capable of traveling at 20 times the speed of sound. The arrowhead-shaped unmanned aircraft, dubbed Falcon Hypersonic Technology Vehicle 2, blasted off from Vandenberg Air Force Base, northwest of Santa Barbara, into the upper reaches of the Earth's atmosphere aboard an eight-story Minotaur IV rocket made by Orbital Sciences Corp.

A lightning-quick experimental aircraft made history when it sped more than 3,000 mph above the Pacific Ocean in a test flight, reigniting decades-long efforts to develop a vehicle that could travel faster than a speeding bullet. The unmanned X-51A WaveRider, which resembles a shark-nosed missile, was launched midair Wednesday off the coast near Point Mugu. It sped westward for 240 seconds, reaching Mach 5.1, or more than five times the speed of sound, before plunging into the ocean as planned.

High above the Mojave Desert, the military's next-generation fighter jet dropped a 2,000-pound bomb for the first time in its latest test flight. It's a key milestone for the stealthy, supersonic F-35, built by Lockheed Martin Corp., which has been undergoing tests since its first flight in late 2006. The F-35, piloted by Air Force Maj. Eric "Doc" Schultz, jettisoned the smart bomb Wednesday from the belly of the aircraft over the Naval Air Weapons Station test range at China Lake.

A test flight of an experimental aircraft traveling at 20 times the speed of sound ended prematurely Thursday morning when the arrowhead-shaped vehicle failed and stopped sending back real-time data to engineers and scientists who were monitoring the mission. The unmanned aircraft, dubbed Falcon Hypersonic Technology Vehicle 2, was meant to test new technologies that could give the Pentagon the capability to deliver non-nuclear military strikes anywhere on the globe in less than an hour.
