Built in Switzerland, The Solar Impulse 2, is the world’s largest solar-powered aircraft and completed a record-breaking 40,000-kilometer flight around the world using only sunlight. Its wingspan is reinforced with 140 carbon-fiber ribs, and it conserves energy by climbing to 8,500 meters during the day to harness solar power and descending to 1,500 meters at night. This journey demonstrated the potential of renewable energy in aviation.

This is a photo taken in 1950s on KLM. At the time, Martin M-130s, Lockheed Constellations, and Douglas DC-6s operated by airlines such as KLM and the now-defunct Trans World Airlines (TWA) had beds in both the upper and lower berths. These beds featured mattresses, Pullman-style curtains for privacy, windows, reading lights, and even breakfast-in-bed service. At the time, a round-trip economy airfare from New York to London on a Boeing 377 Stratocruiser cost about $580 (about $12,000 today) The baggage racks as we know them today were phased in during the late 1960s and early 1970s

Bunk beds on planes in the 1950s, 1960s were a fascinating innovation, offering a unique and luxurious travel experience. These cozy sleeping arrangements allowed passengers to rest comfortably during long flights, transforming air travel into a more restful and enjoyable journey. The concept highlighted the era's emphasis on passenger comfort and creativity in aviation design, making it a memorable and intriguing chapter in the history of air travel.

A 16-YEAR-OLD BOY SHAKES NASA WITH STUNNING IMAGES OF THE MOON

An incredibly detailed image of the Moon was compiled by an Indian teenager, who captured 55,000 photographs — accumulating more than 186 gigabytes on his laptop in the process — to obtain a pastache of celestial proportions.

Prathamesh Jaju, 16, from Pune, Maharashtra, shared his HDR image of a waning crescent moon on Instagram. He admitted that compiling so many photos for his most detailed and sharp image to date tested his technology. "The laptop almost killed me with the processing," he said.

The amateur astrophotographer began the project by filming several videos of different small sections of the Moon in the early hours of May 3. Each video contains about 2000 frames; the trick was to merge and stacking the videos to create a single image, while overlapping them to generate a three-dimensional effect.

"So I took about 38 videos," Jaju explained, according to News 18. "We now have 38 images." "We focus each of them manually and then photoshop them together, like a huge tile."

Jaju told ANI on Twitter that he learned to capture and process those composite images with web articles and YouTube videos. After some touch-ups, the nearly 40-hour processing resulted in an impressive composition of the Moon with magnificent details, rich texture and an amazing range of colors.

Colors, Jaju said, are a fascinating phenomenon. They represent the minerals of the Moon that DSLR cameras can distinguish with greater clarity than the human eye.

"The blue tones reveal areas rich in ilmenite, which contains iron, titanium and oxygen," he said. """While the colors orange and purple show relatively poor regions in titanium and iron.""" White and gray tones indicate areas exposed to more sunlight.

The teenager shared with his tech-savvy followers on Instagram the specifications of his telescope, high-speed USB camera, tripod and lenses, as well as the software he used to capture the images.
Thousands of viewers were impressed by the composite image Jaju obtained.

"Bravo! "It's a beautiful job, aesthetically, astronomically and technologically," said an Instagram user.

"Hats off to you for capturing something so elegant!" ", he wrote another. "This image cannot be properly quantified in any way and should go down in history as the best image of the Moon ever captured from Earth."

In the future, Jaju hopes to become a professional astrophysicist.

Bajau people of Indonesia, Philippines and Malaysia were first recorded by Europeans when Venetian explorer Antonio Pigafetta met them in 1521 AD.

These maritime nomadic people have been fishing and diving for many millennia and over that time they have evolved bigger spleens which allows them to dive for longer than the average human.
According to scientists :
"The bigger spleen makes more oxygen available in their blood for diving. Located close to the stomach, the fist-sized spleen removes old cells from the blood and acts as a biological scuba tank during long dives."

Bajau people can dive to depths of over 200 feet and hold their breath for 13 minutes. They can also walk across the seabed hunting fish. These people live most their lives at sea and are the first known humans genetically adapted to diving.

In the 1960's General Motors was trying to get the freight cost down on Vegas to keep them a budget friendly car. At the time, a new Vega had a price tag around $2,000. Engineers from GM and Southern Pacific Railroad came up with the Vert-A-Pac.

This allowed 30 cars to be shipped per boxcar instead of 18. Lowering freight costs by up to 40%. GM engineers also designed specific oil baffles to keep oil from spilling along with specially designed carburetors, batteries and added plastic spacers between the powertrain and the chassis to prevent damage. Pretty wild, no?
