America to Australia in 6 Hours !!!

 

From America to Australia in Under 6 Hours

Just 100 years ago, getting from America to Europe was a voyage that took several days by ocean liners. With the invention of airplanes, that travel time was significantly shortened to under 24 hours. At the apex of the era of transatlantic flight, the Concorde was able to fly 100 passengers at mach 2.0 speeds from New York to London in just over 3.5 hours.

Now, the European Space Agency (ESA) just greenlighted the next stage of modern transportation – the hypersonic flight. The ESA has approved a new round of funding to project LAPCAT (Long-Term Advanced Propulsion Concepts and Technologies).
Hypersonic Plane

Ignoring its funny name, the new plane will fly at mach 5.0 speeds (that’s five times the speed of sound!), using liquid hydrogen engines. The planes will be able to travel from England to Australia in four hours, carry 300 passengers and even fly to space in just 15 minutes.

The new kind of engine is being developed by the British company Reaction Engines, who is said to invest over 60 million GBP in the development, and are going to start builing a full-scale prototype engine.

Hypersonic Plane

Current jet engines require that airplanes carry liquid oxygen as a coolant because in speeds beyond mach 3.0 the engines cannot use external oxygen for cooling. The new type of engine can use external oxygen freely, allowing it to cool down its engines from over 1,000°c (1,832°f) to -150°c (-328°f) in a fraction of a second.
Hypersonic Plane

Experts are hailing this development as the biggest advancement in aviation since the invention of the jet engine. The cost of a single plane is estimated to be a whopping $1.1 Billion and will have no windows.

The Long-term Advanced Propulsion Concept and Technologies (LAPCAT) was developed by British company Reaction Engines Limited (REL) and funded by the European Space Agency (ESA). The 139-meter long hypersonic plane has four liquid hydrogen-powered Synergistic Air-Breathing Rocket Engine (SABRE) engines and can carry up to 300 passengers.
It can travel up to 6,100 kilometer per hour – five times faster than the Airbus A380. By using liquid hydrogen as fuel instead of fossil fuel it is also greener and would only produce water vapor and nitrous oxide instead of carbon emissions.

The Most Expensive Book In the World !!!

A copy of John James Audubon’s Birds of America was sold at an auction in London for £7.3 million ($11.5 million), and thus became the most expensive book ever sold. The auction was a rare chance to own one of the best-preserved editions of the 19th- century masterpiece, with its 435 hand-colored illustrations. The winning bid was placed by London-based art dealer Michael Tollemache, who outbid three others during the auction.Don’t miss the video of the book at the bottom!
most expensive book
Only 120 complete sets of Audubon’s 435 hand-colored, life-sized engravings of America’s birds are believed to exist today, with the majority (107) owned by institutions. The last full edition of The Birds of America, which went up for auction in 2010, sold for £7.3m at Sotheby’s, breaking the world record for a single book.
most expensive book
“Birds of America is most significant for its sheer beauty. It’s a masterpiece of illustration,” the words of Richard Davies, a rare and used books specialist. “Aside from being famous in the rare book world, Birds of America also has immense historical and ornithological importance. Some of the birds John James Audubon painted are extinct, and he also discovered new species.”
most expensive book
Measuring over three feet in height and running to four volumes, The Birds of America was created by Audubon between 1827 and 1838.  Son of a French sea captain , Audubon was an itinerant artist who traveled America’s wilderness drawing the birds he loved. He was insistent that The Birds of America was made up of life-size illustrations and that it showed all the known species of north America, making the finished volume
most expensive book
Each of the printed books were colored by hand, and it was an extremely laborious process. Even by today’s standards, the vividness of its illustrations of birds is extraordinary but when it was being released in the 1830s it was mindboggling. Audubon employed a rather shocking technique to produce the book. He hunted the birds down and shot them before propping them up on wires to paint. Each drawing would take about 60 hours to complete. Ironically, many of his beautifully rendered subjects are now extinct, such as the Carolina Parakeet, Passenger Pigeon, Labrador Duck, Great Auk, Esquimaux Curlew, and Pinnated Grouse.
most expensive book
Picking up a copy of the “book” is a two-person job, said the dealer, who examined an edition at Sotheby’s once prior to the auction. “The (very nervous) resident expert and I (gingerly) turned the pages together, him at the top and me at the bottom, and peeled them back (respectfully) into just the right conjunction with the rest of the plates,” said Gekoski. “You have to be careful how you handle a gargantuan book worth more than 10 million dollars.”

LZ-129 Hindenburg: …Airships Which Ruled The Skies Prior to Airliners !!!

Prior to the age of the airliner, Zeppelin airships ruled the skies over the north Atlantic — connecting cities like New York with Western Europe. Zeppelin’s fleet of airships included such colossal creations like the Graf Zeppelin and the Hindenburg  along with the less famous Graf Zeppelin II.

Before the modern jumbo jet and its first class suites, the biggest and grandest thing in luxury air travel was the German Zeppelin Airship.

Of all the massive Zeppelin’s constructed, the most famous was the Hindenburg. The Hindenburg was designed to ferry passengers across the Atlantic in serenity, with the dirigible floating smoothly through the clouds.

The Hindenburg was the first of two “Hindenburg” Class airships constructed by the Zeppelin Company. Construction of the airship began in 1931 and was completed in 1936. The Hindenburg, along with its highly successful predecessor, the Graf Zeppelin, made numerous trans-Atlantic crossings in their brief but illustrious career.

Constructed out of an aluminum alloy called duralumin, the Hindenburg’s massive frame work was filled with 7 tons of hydrogen. Hydrogen is much lighter than air, and allows the massive Zeppelin to carry more people in greater levels of luxury. However, with an ignition source, an oxidizer, and right concentration, hydrogen can also be incredibly flammable.

The Hindenburg entered passenger service in May of 1936 and carrier up 50 passengers in luxury across the Atlantic.

The legend of the Hindenburg’s luxurious amenities are well know, but most have not seen them in living color. So take the opportunity to check out these wonderful photos of the Zeppelin’s passengers spaces courtesy of airships.net and the German Federal Archive.
