Drones already rule much of the skies over modern day battlefields, and could someday begin ferrying cargo to forward bases and troops. The U.S. Air Force put out a call this week for a fully autonomous unmanned air vehicle that can deliver cargo within a combat radius of 500 nautical miles.

Los Angelenos have recently watched billowing clouds from a nearby wildfire hover overhead, in scenes reminiscent of "Volcano." NASA's Terra satellite took the opportunity to snap a photo of the smoke monster on the night of August 30. Red outlines in the photo indicate wildfire hotspots.

Forget those cigar-shaped dirigibles of yore. German-American collaboration has produced a tadpole-like airship that could debut within days, and make even a jaded Sky Captain take a second look.

A new unmanned combat aircraft could soon wing its way to the battlefield and land with the precision of a helicopter. The Excalibur recently completed its first flight to demonstrate those abilities using a hybrid turbine-electric propulsion system.

The unmanned aerial system (UAS) could pack a 400-pound payload of four Hellfire missiles, and also deliver weapons or other supplies to warfighters deep in rough territory. Its design allows it to have a maximum speed of 460 mph, but also have the ability to loiter overhead at just 115 mph.

As environmental concerns increasingly shape the direction of technology, the future of aviation is no exception: scientists have been looking to replace fuel-guzzling aircraft with solar-powered variants, an innovation that, in addition to passing the green test, would also enable planes to linger in the sky for longer.

Southern Californians may be living on borrowed time. At least two sections of the notorious San Andreas Fault, a hotbed of tectonic tension, are apparently overdue for a huge earthquake that could devastate Los Angeles County or San Francisco. Though they can neither prevent nor pinpoint it, scientists would like to get as much information as they can as to where and when the next "Big One" could happen. Increasingly, they're turning to air and space to learn what's happening 10 miles underground.

A new radar plane developed at NASA's Jet Propulsion Laboratory is the first American system designed to map earthquake hot zones.

Boeing announced today that they would not hit their latest scheduling target of a first Dreamliner flight before the end of this month, needing to go back to the drawing board for structural reinforcement of a side-of-body panel. This is the latest in a series delays, and it will almost certainly push back the current first-delivery target of Q1 2010.

While watching news footage of a wildfire raging, maybe you've been struck by frustration at the lack of a high-tech, super-sized firefighting solution. Why, in 2009, don't firefighters have access to a super water-cannon? Where is the quick-hardening smothering shell? How much longer will we wait for a mountain-climbing hydro-Roomba?

The answer may be closer than you think. I was treated to a demonstration of the largest firefighting vehicle in the world, the Evergreen Supertanker.

Check out the photos.

It’s designed to seat two, take off and land vertically, fly 10 feet above the ground, and reach 75 miles an hour. It’s about the size of a car, but it’s round instead of boxy. Yup, it’s a flying saucer. Next year, California-based Moller International hopes to introduce the M200G personal recreation craft, the first of what the company expects to be a full line of “volanters”—vertical-takeoff-and-landing aircraft. The design is 300 years in the making.

Imagine a car veering off a lonely mountain road and tumbling down the embankment. Minutes later, a sleek aircraft zooms in quietly at 230 miles an hour, tilts its wings and rotors up, hovers, and sets down just feet from the wreck. The pilot and a medic load the injured driver into the aircraft and zip back to a hospital at twice the speed of a conventional helicopter ambulance.
