Creating a laser that can melt a soda can in a lab is a finicky enough task. Later this year, scientists will put a 40,000-pound chemical laser in the belly of a gunship flying at 300 mph and take aim at targets as far away as five miles. And we're not talking aluminum cans.  
 
Boeing's new Advanced Tactical Laser will cook trucks, tanks, radio stations - the kinds of things hit with missiles and rockets today. Whereas conventional projectiles can lose sight of their target and be shot down or deflected, the ATL moves at the speed of light and can strike several targets in rapid succession.
[video] Colour Like No Other

...whenever we travel to Europe, we wonder why TV commercials over there are, at their best, so much more witty, provocative, and/or beautiful than American TV commercials. Case in point: a new 70-second European spot for Sony’s Bravia TVs...  
 
Synched to a Rossini score,
Colour shows gorgeous explosions of bright blue, green, pink, yellow, and purple paint in and around an abandoned high-rise housing complex in Glasgow.  
 
And it’s
all real, not computer-generated.  
 
A-list music video director Jonathan Glazer (Radiohead, Massive Attack) spent 10 days with a crew of 250 setting up more than 600 explosive devices...and 1,700 detonators linked by 35 miles of copper wire to send 18,000 gallons of paint thrillingly airborne...

Hooah, Troopers  
 
Welcome to Paratrooper.net, a wellspring of knowledge and unending witty commentary regarding the airborne community. Paratrooper.net is a great place for paratroopers to come and relax, unwind and comment on things that maybe only fellow paratroopers would consider 'Normal' (although we just call it being 'Socially Challenged').  
 
For just about 10 years now Paratrooper.net and its early predecessor Airborne On The Web (AOTW) have served as a beacon of maroon in a NAP (Non Airborne Personnel) filled Internet wasteland of 'Regular Army' websites.

What is a Powered Paraglider?  
A Powered Paraglider is a Paraglider with a motor added, allowing launch from level ground. The motor can be a backpack style motor, with launch and landing on the pilot's feet, or on a "trike" or "cart". Paramotor is another name, but it's also a registered trademark of one U.S. manufacturer of powered paragliders.  
 
What's the difference between a Powered Paraglider and a Powered Parachute?  
PPG is a Powered Paraglider, as described above. Foot launched or wheel launched, it has a motor between 15-30 horsepower, and a high performance elliptical wing, the same as used for unpowered paragliding. Control is via hand operated "brakes" on the wing.  
 
PPC is Powered Parachute. These are much larger, usually with a much less efficient rectangular parachute (although elliptical wings are becoming more popular nowadays), always wheel launched, and 40-70 horsepower. Control is via foot operated steering bars which operate the wing brakes.  
 
One more thing: Parasailing is getting towed around the harbor behind a boat, usually in Acapulco after you've had one too many drinks (sometimes referred in PPG circles as "dope on a rope"). In this case you're a passenger on a thrill ride, not a pilot.  
 
Basically strap a big fan to your back, put on a parachute, and run into a strong wind.

Microlights, Ultralights, Trikes, Ultralight Trikes and Hang Gliders.  
 
Airborne specialise in the design and manufacture of ultralights (also called, microlights, trikes or ultralight trikes) and hang gliders, for the serious adventure aviation enthusiast.

During the late 1970s and early 1980s, many people sought to be able to fly affordably. As a result, many aviation authorities set up definitions of lightweight, slow-flying aeroplanes that could be subject to minimum regulation. The resulting aeroplanes are commonly called "ultralight" or "microlight", although the weight and speed limits are rarely the same between any two countries.  
 
There is also an allowance of another 10% on Maximum Take Off Weight for seaplanes and amphibians, and some countries (such as Germany and France) also allow another 5% for installation of a ballistic parachute.  
 
The safety regulations used to approve microlights vary between countries, the most strict being the United Kingdom and Germany, while they are almost non-existent in France and the United States. The disparity between regulations is a major barrier to international trade and overflight, as is the fact that these regulations are invariably sub-ICAO, which means that they are not internationally recognised.  
 
In most affluent countries, microlights or ultralights now account for about 20% of the civil aircraft fleet.

Ultralight flying has become quite popular in the last few years, but as with most things these days, the price of flying is constantly rising. The Affordaplane offers a unique opportunity to trade some of your time for a significant savings in dollars.

The record distance for a human fired from a cannon is 56.54 m (185 ft 10 in), by David "Cannonball" Smith Sr. This human cannonball feat occurred on May 29, 1998, at Kennywood Park, West Mifflin, Pennsylvania, USA. It is estimated David was traveling at over 112 km/h (70 mph) during the flight! Despite all the airtime in his chosen profession, there is not a part of performing that David doesn't enjoy. "I am able to do something that is entertaining for people," he says, "I truly enjoy people!" He has eight children and five of them are human cannonballs! "The others are still too young!" he laughs. Continuing in their father's sky-high tradition is obviously in their blood!

Hang gliding can be dated back to the days of Leonardo da Vinci, whose sketchings portrayed his desire for human flight. Through fact and fiction, silent aviation has played a major role in man's dream to soar with the birds.  
 
From the time of the ill fated flight of Icarus to the turn-of-the-century pioneers of the sport, such as Otto Lilienthal, Octave Chanute and John Montgomery, man has attempted free flight in just about every phase of modern history. As the Wright Brothers continued their pursuit of powered flight, they honed their flying skills in "hang gliders". After their famed Kitty Hawk flight, the world became increasing interested in the technological advances of powered flight, leaving hang gliding for another generation.  
 
Hang gliding didn't emerge again until the 1960's, with the development of Francis Rogallo's "Rogallo wing", a NASA project for a possible recovery system for spacecraft. Little did Francis know that his design was going to begin a rebirth of hang gliding in the early 1970's.  
 
In 1971, the Southern California Hang Gliding Association was born. Through steady evolution of the sport, today we are known as the United States Hang Gliding Association, with a membership base worldwide.

Here's how to create your own personal Stage 2 Smog Alert: Buy an indoor air purifier. Using a popular process called ionization, the air cleaners can actually generate ozone levels in a room that exceed the worst smog days in Los Angeles, a new study finds. The devices are popular in urban areas. They are touted as getting rid of dust, pollen and other airborne particles.
