  1. Most plane crashes are ‘survivable’
    [url=https://kra23c.cc]kraken даркнет[/url]
    First, the good news. “The vast majority of aircraft accidents are survivable, and the majority of people in accidents survive,” says Galea. Since 1988, aircraft — and the seats inside them — must be built to withstand an impact of up to 16G, or g-force up to 16 times the force of gravity. That means, he says, that in most incidents, “it’s possible to survive the trauma of the impact of the crash.”

    For instance, he classes the initial Jeju Air incident as survivable — an assumed bird strike, engine loss and belly landing on the runway, without functioning landing gear. “Had it not smashed into the concrete reinforced obstacle at the end of the runway, it’s quite possible the majority, if not everyone, could have survived,” he says.

    The Azerbaijan Airlines crash, on the other hand, he classes as a non-survivable accident, and calls it a “miracle” that anyone made it out alive.

    Most aircraft involved in accidents, however, are not — as suspicion is growing over the Azerbaijan crash — shot out of the sky.

    And with modern planes built to withstand impacts and slow the spread of fire, Galea puts the chances of surviving a “survivable” accident at at least 90%.

    Instead, he says, what makes the difference between life and death in most modern accidents is how fast passengers can evacuate.

    Aircraft today must show that they can be evacuated in 90 seconds in order to gain certification. But a theoretical evacuation — practiced with volunteers at the manufacturers’ premises — is very different from the reality of a panicked public onboard a jet that has just crash-landed.
    Galea, an evacuation expert, has conducted research for the UK’s Civil Aviation Authority (CAA) looking at the most “survivable” seats on a plane. His landmark research, conducted over several years in the early 2000s, looked at how passengers and crew behaved during a post-crash evacuation, rather than looking at the crashes themselves. By compiling data from 1,917 passengers and 155 crew involved in 105 accidents from 1977 to 1999, his team created a database of human behavior around plane crashes.

    His analysis of which exits passengers actually used “shattered many myths about aircraft evacuation,” he says. “Prior to my study, it was believed that passengers tend to use their boarding exit because it was the most familiar, and that passengers tend to go forward. My analysis of the data demonstrated that none of these myths were supported by the evidence.”

  2. The survivors of recent crashes were sitting at the back of the plane. What does that tell us about airplane safety?

    Look at the photos of the two fatal air crashes of the last two weeks, and amid the horror and the anguish, one thought might come to mind for frequent flyers.

    The old frequent-flyer adage is that sitting at the back of the plane is a safer place to be than at the front — and the wreckage of both Azerbaijan Airlines flight 8243 and Jeju Air flight 2216 seem to bear that out.

    The 29 survivors of the Azeri crash were all sitting at the back of the plane, which split into two, leaving the rear half largely intact. The sole survivors of the South Korean crash, meanwhile, were the two flight attendants in their jumpseats in the very tail of the plane.

    So is that old adage — and the dark humor jokes about first and business class seats being good until there’s a problem with the plane — right after all?

    In 2015, TIME Magazine reporters wrote that they had combed through the records of all US plane crashes with both fatalities and survivors from 1985 to 2000, and found in a meta-analysis that seats in the back third of the aircraft had a 32% fatality rate overall, compared with 38% in the front third and 39% in the middle third.

    Even better, they found, were middle seats in that back third of the cabin, with a 28% fatality rate. The “worst” seats were aisles in the middle third of the aircraft, with a 44% fatality rate.
    But does that still hold true in 2024?

    According to aviation safety experts, it’s an old wives’ tale.

    “There isn’t any data that shows a correlation of seating to survivability,” says Hassan Shahidi, president of the Flight Safety Foundation. “Every accident is different.”

    “If we’re talking about a fatal crash, then there is almost no difference where one sits,” says Cheng-Lung Wu, associate professor at the School of Aviation of the University of New South Wales, Sydney.

    Ed Galea, professor of fire safety engineering at London’s University of Greenwich, who has conducted landmark studies on plane crash evacuations, warns, “There is no magic safest seat.”

  3. The most exciting new trains coming in 2025

    Amazing adventures, extraordinary landscapes and fabulous cuisine — the world’s greatest railway journeys are an unforgettable experience that can immerse you in the culture of a new country.

    Demand for luxury “land cruise” trains with five-star hotel-style accommodation is booming. 2025 will see several new trains take to the rails for the first time, offering new opportunities to explore Italy, France, Saudi Arabia and the United Kingdom.

    But the best railway journeys don’t have to be the most expensive. There’s an ever-evolving world of train trips out there. Here are some of the key developments in the coming year
    Two of Europe’s great capitals are now linked by their first direct high-speed train connection. Germany’s Deutsche Bahn introduced a daytime InterCity Express (ICE) service between Paris and Berlin on December 16 and is planning to add a second route between the two capitals in 2026.

    Taking advantage of its new fleet of 200 mph (322 kph) ICE3neo trains, the once-a-day service takes around eight hours in each direction, also serving Strasbourg, Karlsruhe and Frankfurt on its 546-mile (878-kilometer) journey.

    Fares start from around $60, and each train has capacity for 444 passengers, of which 111 can enjoy the additional comfort of leather seats and at-seat refreshments in first class.

    The new high-speed ICE service is the first direct daytime train between Paris and Berlin since the 1990s and complements the Nightjet sleeper service introduced in 2023.

    It may not be as fast as flying — some of the journey has to use lower speed “classic” lines to bridge gaps in the European high-speed network — but it is undoubtedly a more sustainable and more stylish way to travel across Europe.

  5. Chile’s President Boric leads journey to South Pole in historic trip
    [url=https://kra23s.cc]kraken darknet[/url]

    Chile’s President Gabriel Boric travelled to Antarctica’s South Pole on Friday, a place where no other Latin American president has set foot, according to the Chilean government.

    Boric led the historic two-day trip, named Operation Pole Star III, to extend the environmental monitoring of pollutants on Antarctica, Chile’s government said in a statement.

    He travelled with scientists, armed forces commanders and government ministers from the Chilean capital of Santiago to Punta Arenas, a city in southern Chile, public broadcaster Television Nacional de Chile (TVN) reported. From there, they made several stops before finally reaching the US-run Amundsen-Scott South Pole Station, according to TVN.

    Chile is one of seven countries that has a territorial claim in Antarctica, alongside Argentina, Australia, France, New Zealand, Norway and the United Kingdom.

    It is also a signatory of the Antarctic Treaty, which dictates that the continent may only be used for peaceful and scientific purposes.

    While Chile has historically carried out scientific activity in Antarctica’s northern sector, the country’s government is now hoping to expand research into the west of the continent, its statement said.
    Boric called his trip to the South Pole an “honor” and a source of pride, TVN reported.

    “This is a milestone for us. It is the first time a Chilean and Latin American President has visited the South Pole,” he said, according to TVN.

  6. On a long-dormant pad in Florida, a rocket that could challenge SpaceX’s dominance is poised to launch
    [url=https://kra23s.cc]kraken официальный сайт[/url]

    On a Florida launchpad that has been dormant for almost two decades, a new, roughly 320-foot (98-meter) rocket — developed by Jeff Bezos’ company Blue Origin — is poised for its maiden flight.

    The uncrewed launch vehicle, called New Glenn, will mark Blue Origin’s first attempt to send a rocket to orbit, a feat necessary if the company hopes to chip away at SpaceX’s long-held dominance in the industry.

    New Glenn is set to lift off from Cape Canaveral Space Force Station as early as next week.

    The rocket, which stands about as tall as a 30-story building, consists of several parts: The first-stage rocket booster gives the initial thrust at liftoff. Atop the booster is an upper rocket stage that includes a cargo bay protected by a nose cone that will house experimental technology for this mission.

    And, in an attempt to replicate the success that SpaceX has found reusing rocket boosters over the past decade, Blue Origin will also aim to guide New Glenn’s first-stage rocket booster back to a safe landing on a seafaring platform — named Jacklyn for Bezos’ mother — minutes after takeoff.

    Like SpaceX, Blue Origin will seek to recover, refurbish and reuse first-stage rocket boosters to drive down costs.

    For this inaugural mission, a smooth flight is not guaranteed.

    But the eventual success of New Glenn, named after storied NASA astronaut John Glenn, is instrumental to some of Blue Origin’s most ambitious goals.

    The rocket could one day power national security launches, haul Amazon internet satellites to space and even help in the construction of a space station that Blue Origin is developing with commercial partners.

  7. Its such as you read my thoughts! You seem to know a lot approximately this,
    such as you wrote the book in it or something. I feel that you simply could do with a few p.c.

    to power the message home a bit, but other than that, that is excellent blog.
    A fantastic read. I’ll certainly be back.
