How can this be? Inflight email service and instant messaging? Free? What has the world come to? Are there no more terrorist threats out there? Just imagine the way a conversation would go via Yahoo!'s IM between any random Arab terrorist (I'm not racially profiling, it's just that this is how they ar... |

Swifts are amongst the fastest birds, and even if they resemble swallows, they are in fact related to hummingbirds. A swift weighs a few tens of grams, but with its sickle shaped wings they can reach 160 km (100 mi) per hour. Swifts are the birds the term aerial suits best as they catch food (insects), eat, drink, co... |

Mammals and birds may be the most complex organisms, but insects have won the evolution race. There are about 900,000 described species, and scientists evaluate their real number from 2 to 10 million species. Calculating the total number of insects on the globe, researchers found it overpasses by 200 billion times th... |

Butterflies are renowned usually for their beauty. But amongst the 750 species of butterfly encountered in US and Canada, this is the most known worldwide, due to its amazing migration records. The black and orange beauty bears the name of monarch butterfly because the first English settlers of America associated it ... |

Bird flight has fascinated humans since ever. And by over 150 years, with the discovery of the oldest bird, Archaeopteryx, a vivid debate divides scientists into two camps: those who say birds evolved from ground-dwelling ancestors and developed flight by taking off from the ground and those saying that birds evolved... |

1.Hummingbirds are found only in Americas, from Alaska to Tierra del Fuego (in the southern tip of South America). Half of the hummingbird species (160) live in the Amazon forest. The northernmost species is the rufous hummingbird (Selasphorus rufus), the only species that reaches Alaska. The southernmost species is ... |

In fairy tales, the characters turn into flies and get everywhere they want, listening to what's cooking behind any door. Now, when you say 'there are bugs in this room', you automatically send a message with double meaning, one of which is related to the new-generation devices. Lately, increasingly mo... |

This is many people's dream: traveling comfortably by plane, but paying for a very cheap ticket (just 9 to 139 Euro / $ 12-195). The low cost companies have developed a lot lately, taking advantage of our desire to arrive fast and safe to whatever location in the world. You almost pay for an plane ticket as much... |

Without a map or GPS, we are completely lost in the middle of nowhere. But many species, such as the mole rat, birds, fish, amphibian, have a magnetic compass. Bats have it too, and a new research shows how these mammals can feel the polarity of a magnetic field, detecting the difference between north and south. This... |

This monster is much bigger that any helicopter ever built: the Soviet Mil V-12 was a doubled version of Mi-6 fitted with greater fixed-wing airlift of An-22 and Il-76. It used a double set of Mi-6 dynamics: two sets of Mi-6 engines, gearboxes and lifting rotors side-by-side, with small overlap. Rotor rpm decreased t... |

The skies during the dinosaur era were not dominated by birds, like it happens in our times, but by huge prehistoric hairy flying reptiles called pterosaurs. Many of them were fish-eaters and are often pictured as skimming along the surface of water while flying with their mouths open, fishing the way modern skimmers... |

The top speed for airplanes could be limited by physical rules of aerodynamics, but the birds' flight is much more complex, breaking those rules. Many think that the fastest speeds at which the smallest insects and the largest aircraft can fly are strongly connected to their weight and their wingspan. A team led... |

There are three groups of living animals that we associate with the flight: birds, bats and insects. But there are also other groups of animals that can manage to take off and "defeat" gravitation on shorter or longer bursts. They are generally called gliders. Here are classical examples. 1. There are over 52 specie... |

Have you ever imagined a plane flapping its wings in the bat style?The flexible flight of the bats, so different from the rigid wing beat of the birds, could be a model for new versatile aircrafts.A Swedish research resembles a previous American one, in trying to set up the details of the sophisticated bat flight in ... |

This is particularly difficult for human pilots master formation flight: it takes years of practicing. But for migratory birds that's piece of cake. 65 % of the birds species do migrate. The way birds migrate varies a lot: some will do it alone (like the cuckoo), others in pairs, while others in large flocks. T... |

YouTube recently released a new contest for all the 18 to 22-year-old users, allowing them to win a free flight with AirTran Airways by posting a video on the page. Because the company is now looking for a new cheer, it signed a deal with YouTube and released a contest to bring even more video content to the page. Al... |

People enjoy flying. This pleasure comes like a shout since the antiquity, with the myth of Daedalus. And ballooning brings you closer to a real sensation of hovering. But do not think that humans are the only wingless beings able to fly. Spiders too enjoy ballooning and thousands of flying spiders can flood a terrai... |

Boomerangs were the world's first heavier than air flying machines. Though when you say boomerang you think of Australian Aborigines, who have used both boomerangs and hunting sticks for many thousands of years, research has shown that ancient tribes in Europe used special throwing axes. Also, in ancient Egypt,... |

A marathon is like a warm-up exercise for some animal species. Their endurance capacities can amaze, like they would be driven by engines. Now, a new record for endurance has been tracked in four bar-tailed godwits for a non-stop flight of over 10,000km (6,000 mi) from New Zealand to the Yellow Sea (eastern China).Th... |

Scientists have recently discovered a lizard shockingly similar to current flying dragons roaming the air during the dinosaur era. Exactly like in the flying dragons, the ancient arboreal lizard presents a wing-like membrane stretched across elongated ribs. Named Xianglong zhaoi, the gliding lizard lived during the E... |

65 % of the bird species migrate. The ancients, like Aristotle for example, thought that during the winter birds go inside the mud of the bottom of the swamps or in caves, where they pass the winter, and reemerge in the spring. In the 13th century, the German emperor Frederick the Second, passionate hunter, was the f... |
