Sometimes things, purely odd, happen. However the disaster on September 6, 1952, prompted the introduction of stringent safety measures to protect spectators at air shows and no member of the public has been killed at a British air show since.

At the Farnborough Air Show in Hampshire on 6 September 1952, thousands of spectators watched as a De Havilland 110 aircraft broke the sound barrier and then disintegrated in the sky above them and fell to earth. The De Havilland 110 fighter had just broken the sound barrier when it broke up over the spectators, showering them with debris. Among the dead are the pilot, John Derry, and the flight test observer Anthony Richards. The two airmen had completed one fly-past in which they amazed 130, 000 spectators by breaking the sound barrier to produce a sonic boom.

BELÉM, Brazil, Jan 27 (IPS) - A human banner made up of more than 1,000 people, seen and photographed from the air, sent the message "SOS Amazon" to the world, in the first action taken by indigenous people hours before the opening in northern Brazil on Tuesday of the 2009 World Social Forum (WSF).

The mass message reflects "our concern about global warming, whose impact we will be the first to feel, although we, the peoples of the Amazon, have protected and cared for the forests," Francisco Avelino Batista, an Apurinán Indian from the Purus river valley in the Brazilian Amazon, told IPS.

The Disappearing Rainforests

We are losing Earth's greatest biological treasures just as we are beginning to appreciate their true value. Rainforests once covered 14% of the earth's land surface; now they cover a mere 6% and experts estimate that the last remaining rainforests could be consumed in less than 40 years.

* One and one-half acres of rainforest are lost every second with tragic consequences for both developing and industrial countries.

* Rainforests are being destroyed because the value of rainforest land is perceived as only the value of its timber by short-sighted governments, multi-national logging companies, and land owners.

* Nearly half of the world's species of plants, animals and microorganisms will be destroyed or severely threatened over the next quarter century due to rainforest deforestation.  read more »

The Macintosh - the first to bear the name - turns 25 on 24 January. The machine debuted in 1984 and kicked off a product line that were Apple's flagship computers for many years.

The Macintosh helped popularize the combination of graphical interface and mouse that is ubiquitous today. It had a revolutionary all-in-one design, and crucially, used a graphical user interface to navigate around, rather than text commands. This enabled the Apple Macintosh to cross the species barrier – everyday users could now use the computer, rather than just geeks au fait with scripting and coding. Indeed, the $2,495 price tag was perhaps the only barrier to entry.

The mouse input system and simple GUI enabled users to carry out a range of tasks that had been impossible on other computers. The Apple Macintosh came bundled with two software programs, MacWrite and MacPaint, signalling the birth of word processing and desktop publishing. With just 128KB of memory and a sloth-like 8MHz processor, the Apple Macintosh is woefully underpowered by today’s standards, but was cutting edge at the time.  read more »

The Antarctic Peninsula juts into the Southern Ocean, reaching farther north than any other part of the continent. The southernmost reach of global warming was believed to be limited to this narrow strip of land, while the rest of the continent was presumed to be cooling or stable.

Not so, according to a new analysis involving NASA data. In fact, the study has confirmed a trend suspected by some climate scientists. "Everyone knows it has been warming on the Antarctic Peninsula, where there are lots of weather stations collecting data," said Eric Steig, a climate researcher at the University of Washington in Seattle, and lead author of the study. "Our analysis told us that it is also warming in West Antarctica."

The finding is the result of a novel combination of historical temperature data from ground-based weather stations and more recent data from satellites. Steig and colleagues used data from each record to fill in gaps in the other and to reconstruct a 50-year history of surface temperatures across Antarctica.  read more »

WASHINGTON - President Barack Obama was inaugurated yesterday as the 44th president of the United States, seizing the historic moment to invoke the "price and the promise of citizenship" and demand the participation of all Americans in restoring the country to greatness. He took the oath of office on Abraham Lincoln's Bible before a sea of more than 1 million people that stretched from the Capitol building to the Lincoln Memorial. He struck a solemn tone in warning of the challenges and sacrifices that lie ahead. Comparing the economic crisis and fight against terrorism to the trials faced by the Founding Fathers, Obama implored his fellow citizens to join him "in the work of remaking America."

"On this day, we gather because we have chosen hope over fear, unity of purpose over conflict and discord," Obama said, his voice reverberating throughout the National Mall. "Let it be said by our children's children that when we were tested, we refused to let this journey end - that we did not turn back, nor did we falter."  read more »

The fantasy of spy novels and science fiction films is at last becoming reality with a vehicle that can turn from car to aircraft in 15 seconds

It is the ultimate off-roader and it is coming to an airstrip near you. The Terrafugia Transition is a two-seater plane that at the touch of a button converts into a road-legal car. It takes its maiden flight next month and is scheduled to hit the showrooms by next year. “It’s like a little Transformer,” says Carl Dietrich, the Terrafugia boss, proudly. “This is the first really integrated design where the wings fold up automatically and all the parts are in one vehicle. All we have is one simple folding wing, and that means the Transition takes just 15 seconds to switch between flying and driving.”

The Terrafugia Transition is a light sport airplane with four wheels and foldable wings that span 27.5ft when extended. It can soar up through the skies just like a regular aircraft then land on the ground, fold up its two wings and drive down the road at highway speeds. Measuring 19 feet long, it has an airborne range of 460 miles and can cruise at 115mph. According to early reports, the plane uses unleaded gasoline - no rocket fuels necessary. It runs via the 100 horsepower four-stroke Rotax 912S engine.  read more »
