Concorde 002 icing trials. In the 1970s, engineers used a modified Canberra bomber from Boscombe Down as an airborne "icing tanker" to test Concorde prototype 002's deicing systems-spraying water ahead to artificially create ice clouds. One trial also hit a lightning strike.👀

OTD in 1969, the very first British-built Concorde prototype —Concorde 002— took to the skies for its maiden flight. Flown by chief test pilot Brian Trubshaw, the quick 22-minute trip was a huge milestone for the joint UK-France supersonic project. A massive crowd of reporters showed up at the Filton airfield to catch a glimpse of the action. Even Trubshaw, who usually shied away from the press, was thrilled, calling the smooth flight "wizard—a cool, calm, and collected operation." After taking off from Filton, the plane actually had to touch down about 50 miles away at RAF Fairford. As it turned out, the runway at the factory simply wasn't long enough to safely test-fly the massive new supersonic jet! 📹British Pathé ℹ️Concorde Legacy

The difference between de-icing and anti-icing ❄️✈️ Pilots are required to ensure that the wings and all control surfaces are clear of any form of frozen contamination. Even small amounts of ice on the wing can significantly reduce its lift capability as well as the stalling angle of attack. De-icing fluid is used when the aircraft is contaminated with snow or ice which needs to be removed, but no further freezing precipitation is expected before departure. This can be accompanied by spraying heated fluid onto the aircraft to remove the contamination. If protection from further frozen contamination buildup is required, such as when it’s snowing, we then spray a second fluid over the clean wing, which adheres to the wing and prevents the buildup for a period of time. This time of protection is called the ‘holdover time’ Pilots calculate the holdover time for the fluid used by using tables and entering the fluid type, concentration, type of precipitation and temperature. As a general rule, the higher the number of the fluid used, the longer the holdover time. Eg Type 2 fluid offers a shorter holdover time than Type 4. The fluids can also be diluted to offer varying levels of protection. Eg 75/25 - This means that the mixture being used consists of 75% de-icing fluid and 25% water. The longest holdover time is achieved by using 100% fluid but this can be less environmentally friendly and very expensive. So if we can achieve the desired holdover time with a lower dilution, we can enhance the efficiency of the operation. 📸 by ig/airlinepilotperformance , iarild

Ukraine’s Unmanned Systems Forces strike an enemy UAV depot, aircraft, and radar in Crimea On April 2, operators of the 1st Separate Center of the Unmanned Systems Forces (1st Separate USC ), jointly with Ukraine’s Defence Intelligence, carried out a series of operations against military targets in temporarily occupied Crimea. The strikes were conducted in coordination with the DeepStrike Center. A storage facility for Orion-type UAVs was hit. The Orion is a reusable strike-reconnaissance drone worth over $5 million, capable of carrying missiles and aerial bombs and remaining airborne for up to 24 hours. The destruction of four Orion UAVs has been confirmed. An An-72P aircraft was also hit. This maritime patrol aircraft is used to monitor coastal areas and detect violations of territorial waters. The third target was a P-37 “Mech” radar station, designed to detect aerial targets, vector fighter aircraft, and provide target designation for surface-to-air missile systems. The precision of USF operations and their carefully planned execution are degrading the enemy’s military potential faster than it can be restored. USF: One Step Ahead!

Operators of the Unmanned Systems Forces struck two Tor-M2 SAM systems worth $50 million On one of the active front sectors, operators of the 412th Nemesis Regiment of the USF detected and hit two enemy Tor-M2 surface-to-air missile systems. As a result of the attack, one launcher was destroyed and the other sustained severe damage. The Tor-M2 is a short-range SAM system used by the enemy as part of layered air defense to cover troops and facilities from Ukrainian aircraft, missiles, and UAV strikes, as well as to protect medium- and long-range air defense systems such as the S-300 and S-400. Its interception radius for aerial targets is up to 15 km. The cost of a new launcher is about $25 million. Operators of the 412th Regiment carried out another #AirDefenseCide against the enemy, using an innovative solution, the details of which are not being disclosed. USF: One Step Ahead

Currently the only flying B-57 Canberra in the world. One of three WB-57s with NASA returning to Ellington Field in Houston, near NASAJohnson. This incredible high-altitude aircraft has been assigned to flying the NOAA SABRE mission to map atmospheric science data. The other two are undergoing maintenance and inspection. One of which had a wheels-up belly landing at Ellington Field in January of this year. The other hasn't flown since 2022, but may re-enter service soon after a period of major inspections. It's based on the Martin B-57 Canberra designed in the 1950s as a tactical bomber. And originally derived from the English Electric Canberra of the 1940s. This one, N926NA, was registered with the US Air Force as 53-3974. It was re-registered 63-13503 when it was converted by General Dynamics to a high altitude reconnaissance RB-57 Canberra in 1965. It then made its way into NASA's hands in 2003, after a period in the 'boneyard' at Davis-Monthan AFB in Arizona. It has also been used to capture solar eclipses. I'll drop a link in the comments to a great article on this.

This video shows an extraordinary coincidence in aviation history..... One of the Concorde's final flights was captured unintentionally, without planning or ceremony - just a camera in the right place at the right time. As the supersonic jet passes through the frame, it represents the closing chapter of an era when commercial air travel briefly defied the limits of speed. Today, Concorde exists only in museums and memories, making moments like this even more powerful. When Concorde made its first commercial departure from Heathrow on January 21, 1976, it was a moment that captured global imagination. Born of Anglo-French collaboration, the sleek white jet embodied not only technical genius but also a shared vision of progress in an era still buzzing with the optimism of the Space Age. Its distinctive droop-nose design, developed to aid visibility during takeoff and landing, became an icon in itself, while its ability to soar at 60,000 feet allowed passengers to glimpse the curvature of the Earth. This blend of aesthetics and performance made Concorde unlike any other aircraft of its time. The Concorde, a supersonic passenger jet that was a joint Anglo-French project. It was renowned for being the first passenger plane to fly faster than the speed of sound, reaching speeds of Mach 2.04 (over twice the speed of sound). Concorde significantly reduced transatlantic flight times, making the journey between London/Paris and New York possible in about three hours. It was in service from 1976 to 2003, primarily flying routes between London, Paris, New York, and Barbados. Developed through a collaboration between British Aerospace and Aérospatiale for the airframe, and Rolls-Royce and SNECMA for engines, Concorde was considered a technological masterpiece. After a fatal crash in 2000 and declining passenger numbers, the remaining planes ceased flights in 2003. The drama of takeoff was unforgettable. Heathrow’s runways would tremble under the roar of its Olympus 593 turbojet engines, a sound so powerful it echoed across West London. Residents and aviation enthusiasts alike would pause to watch the jet thunder down the runway, trailing a streak of heat and sound before lifting sharply into the sky. For the privileged few onboard, the experience was no less thrilling—menus boasted fine wines and gourmet cuisine, while the cabin hummed with the quiet exclusivity of royalty, business magnates, and celebrities en route to New York or Paris in less than half the usual time. Though Concorde’s era ended in October 2003, its legacy remains deeply tied to Heathrow. For nearly three decades, it was both a marvel and a symbol of human ingenuity, demonstrating what was possible when engineering ambition met cultural aspiration. Today, preserved Concorde aircraft at museums around the world remind visitors of an age when the boundaries of speed and style were pushed to new horizons, and every takeoff from Heathrow carried with it the promise of the extraordinary. © Reddit #archaeohistories

"THE WORLD'S MOST POWERFUL NUCLEAR BOMB" Regarded as the most powerful nuclear weapon ever created and tested, the Tsar Bomba was detonated by the Soviet Union on October 30, 1961. It generated a yield of about 50 megatons of TNT, equating to nearly 3,300 times the strength of the "Little Boy" bomb that was released over Hiroshima. The test took place over the Mityushikha Bay site on the remote island of Novaya Zemlya in the Russian Arctic. A specially modified Tu-95V bomber dropped the 27-ton bomb from an altitude of 34,000 feet. A massive parachute was used to slow its descent, giving the crew a 50% chance of escape. 👀

The proboscis monkey is one of the most unique primates in the animal kingdom, easily recognized by its large nose and strong connection to riverine forests. Found mostly around water, these monkeys are surprisingly skilled swimmers, often leaping from trees into rivers to escape predators or move between areas. But the waters they rely on can also be their greatest danger. Crocodiles are silent and patient predators, perfectly adapted to ambush anything that comes within reach. With powerful jaws and lightning-fast reflexes, they wait just beneath the surface for the perfect moment to strike. In this video, that moment comes with devastating precision. As the proboscis monkey attempts to leap from a tree into the water, it falls directly into the path of a waiting crocodile. In an instant, the predator strikes, turning what should have been an escape into a fatal mistake. It’s a chilling reminder that in the wild, survival often depends on timing—and sometimes, one wrong move is all it takes.

Unmanned Systems Forces Destroyed Three SAM Systems in Kursk Region in Just 12 Hours In the Kursk region, operators from the 413th 'Raid' Battalion of Unmanned Systems, along with the consolidated UAV unit "Zhmil" of the 78th Air Assault Regiment, detected and struck three enemy "Buk" air defense systems within just 12 hours. Specifically, pilots executed a precise FPV drone strike on a Buk-M2 Transporter Erector Launcher and Loader (TELAR) that had been camouflaged among a tree line. The strike resulted in a detonation of the missiles, leading to the destruction of the unit. Additionally, the operators damaged the radar systems of two Buk-M3 launchers. The radar is a vital part of an air defense system, as it illuminates aerial targets and guides missiles. Disabling it significantly reduces the system's combat effectiveness. The Buk-M3 (9K37M3 / SA-17 Grizzly) is a modern mobile surface-to-air missile system used by the Russian Federation and is one of the crucial components of its air defense network. It can engage targets at altitudes of up to 35 km and track them from distances of up to 70 km. The entire system is estimated to be valued at around $45 million. USF: One Step Ahead!

On Jan 13, 1982, Air Florida Flight 90, a Boeing 737-200 (N62AF), crashed into Washington D.C.’s 14th Street Bridge moments after takeoff from National Airport. The jet struck 7 vehicles and plunged into the icy Potomac River — killing 78 people, including 4 motorists. The NTSB found pilot error as the cause: the crew failed to properly deice, left engine anti-ice systems off, used reverse thrust in a snowstorm, and tried to melt ice using the jet exhaust of another aircraft. Only 5 people survived — including flight attendant Kelly Duncan. Passenger Arland D. Williams Jr. heroically helped others escape before drowning. President Reagan later honored the rescuers’ bravery in his State of the Union address. A reminder of why deicing is crucial.

💥 Unmanned Systems Forces struck one of the largest refineries in southern russia In the night of 26 September, operators of the 14th UAS Regiment of the Unmanned Systems Forces, in cooperation with other components of the Defence Forces, carried out a strike on the “Afipsky oil refinery” in Krasnodar Krai, russian Federation, located about 380 km from the front line. The Afipsky refinery is one of the key oil-processing enterprises in southern russia. Its design capacity is 6.25 million tonnes of crude oil per year (about 2.2% of russia’s total). The plant’s main products are gasoline, diesel and aviation fuel, which are used to supply the Russian army. As a result of the #DeepStrike, the primary crude oil processing unit AT-22/4 was hit. In 2013 it was modernized, increasing its throughput to approximately 3 million tonnes/year. If it is put out of operation, crude oil processing will stop and fuel output will drop sharply. A fire broke out on the site of the enterprise. Representatives of local authorities have confirmed a hit on one of the technological units. Detailed consequences of the strike are being clarified. The Unmanned Systems Forces are steadily degrading the enemy’s ability to supply fuel and lubricants to the russian army and to continue aggression against Ukraine. 🇺🇦 Unmanned Systems Forces: One step ahead!

Ukraine continues applying long‑range sanctions in response to Russian strikes. Last night, the warriors of our Defense Forces hit targets across different regions of Russia that are fueling this war. Once again, a plant in Kirov was struck – the one supplying components for the weapons Russia uses to attack our people. That’s about 1,200 kilometers from Ukraine’s border. Also hit were an oil refinery in Tyumen, a logistics facility in Yekaterinburg, and a fuel and lubricants depot in Rostov‑on‑Don. We also achieved very strong results with long‑range strikes in the Caspian Sea – including vessels used in military cargo shipments involving Iran, as well as a warship. Thank you for these results! Glory to Ukraine!

Once again, a plant in Kirov was struck – the one supplying components for the weapons Russia uses to attack our people. That’s about 1,200 kilometers from Ukraine’s border. Also hit were an oil refinery in Tyumen, a logistics facility in Yekaterinburg, and a fuel and lubricants depot in Rostov‑on‑Don. We also achieved very strong results with long‑range strikes in the Caspian Sea – including vessels used in military cargo shipments involving Iran, as well as a warship. Thank you for these results! Glory to Ukraine!
