| Most plane crashes are ‘survivable’
kra23 cc
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 |

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

| Scientists have identified an estimated 10% of all species on Earth. Heres what they found in 2024

A toothy toadstool. A vegetarian piranha with a distinctive mark. And a pygmy pipehorse floating in the Indian Ocean shallows.
These wild wonders were among the hundreds of previously unknown species of animals, plants and fungi that scientists named and described for the first time in 2024, expanding our surprisingly limited knowledge of Earths diversity.
Scientists estimate that weve identified only one-tenth of all species on Earth, said Dr.
Shannon Bennett, chief of science at the California Academy of Sciences, in a statement.

While it is critical to place protections on known threatened species, we must also allocate resources towards identifying unknown species that may be just as important to the functioning of an ecosystem, Bennett said.
Researchers connected to the institution described 138 new species in 2024, including 32 fish. One standout was a pygmy pipehorse named Cylix nkosi. The seahorse relative was originally found in 2021 in the cool temperate waters surrounding the North Island of New Zealand, but the species described this year was discovered in the subtropical waters off South Africa, expanding the known range of this group to the Indian Ocean |

| What’s on board this flight
Blue Origin had planned to launch a pair of Mars-bound satellites on behalf of NASA for the first flight of New Glenn.
But delays with the rocket’s development prompted the space agency to change course, moving that flight to this spring at the earliest. So for this inaugural flight, Blue Origin opted to instead fly a “demonstrator” that will test technology needed for the company’s proposed Blue Ring spacecraft — which will aim to serve as a sort of in-space rideshare vehicle, dragging satellites deeper into space when needed.

The demonstrator on this New Glenn flight will remain aboard the rocket for the entire six-hour flight, Blue Origin said, and it will validate “communications capabilities from orbit to ground” as well as “test its in-space telemetry, tracking and command hardware, and ground-based radiometric tracking.”
The Blue Ring Pathfinder demonstrator is part of a deal Blue Origin inked with the US Department of Defense’s Defense Innovation Unit.

Why Blue Origin wants to reuse rockets
Similar to SpaceX, Blue Origin is aiming to recover and refly its first-stage rocket boosters in a bid to make launches less expensive.
“Reusability is integral to radically reducing cost-per-launch,” the company said in a recent news release, |
