 +== I listened to air traffic control while watching the planes live, and now I can’t stop ==
 +
 +Gregory Gibson - May 24, 2026, 6:00 AM EDT
 +
 +Radio is one of those hobbies that quickly turns a five-minute experiment into an entire evening, which is why I keep coming back to it again and again. As an amateur radio operator myself, I love the hunt for finding signals and attaching all that noise and speech to real-world infrastructure.
 +
 +Adding live aircraft into that mix meant I was basically doomed to spend a lot of time matching air traffic control transmissions to real-time aviation events. Unfortunately for me, I live in the middle of nowhere, well out of range of any airport large enough to make use of my own gear for airband listening.
 +
 +So, I went hunting online for public Software Defined Radio (SDR) receivers close to major airports that covered the VHF airband frequency, the capability of receiving signals using AM mode, a waterfall display to see active signals, and a trusty online flight tracking map alongside it. After a few hours, I found the perfect combination, and I was hooked.

 +
 +<blockquote>
 +The wreckage of a Pan American Airways plane has been found 74 years after it plunged into the Atlantic Ocean in a crash that prompted mandatory airline safety briefings. The Clipper Endeavor was found 2,000ft (610m) below sea level off the coast of Puerto Rico with a sonar-equipped drone. It went down on April 11, 1952, following multiple-engine failure shortly after take-off.
 +
 +Everyone onboard survived the impact -- but passengers struggled to locate life vests and rafts as the plane rapidly sank. Of the 69 passengers and crew onboard, just 17 survived. The disaster led to sweeping reforms in aviation safety, including compulsory pre-flight safety briefings on every commercial flight. [...] Today, before every commercial flight, cabin crew are required to outline where a plane's exits are, as well as the location of life vests and how to inflate them.

 +== Air France, Airbus Guilty of Corporate Manslaughter In 2009 Air France 447 Crash ==
 +
 +Posted by EditorDavid on Saturday May 23, 2026 12:34PM

 +Long-time Slashdot reader UnknowingFool shares this report from the BBC:
 +
 +<blockquote>
 +Air France and Airbus have been found guilty of manslaughter over a 2009 plane crash which killed 228 people. The Paris Appeals Court found the airline and aircraft manufacturer "solely and entirely responsible" for the incident, in which flight AF447 from Rio de Janeiro to Paris crashed into the Atlantic Ocean. The passenger jet stalled during a storm and plunged into the water, killing all on board. A court had previously cleared the companies in April 2023, but they were found guilty on Thursday after an eight-week trial.

 +
 +In 2012, French investigators found a combination of technical failure involving ice in the plane's sensors and the pilots' inability to react to the aircraft stalling led to it plunging into the sea. The captain was on a break when the co-pilots became confused by faulty air-speed readings. They then mistakenly pointed the nose of the plane upwards when it stalled, instead of down. Investigators concluded the co-pilots did not have the training to deal with the situation. Pilot training has since been improved and the speed sensors replaced.

 +Sofia Ferreira Santos - 21 May 2026
 +
 +Air France and Airbus have been found guilty of manslaughter over a 2009 plane crash which killed 228 people.
 +
 +The Paris Appeals Court found the airline and aircraft manufacturer "solely and entirely responsible" for the incident, in which flight AF447 from Rio de Janeiro to Paris crashed into the Atlantic Ocean.
 +
 +The passenger jet stalled during a storm and plunged into the water, killing all on board.
 +
 +A court had previously cleared the companies in April 2023, but they were found guilty on Thursday after an eight-week trial. Both have repeatedly denied the charges and say they will appeal.
 +
 +All 12 crew members and 216 passengers on board the flight were killed when the plane crashed into the sea from a height of 38,000ft (11,580m), making it the deadliest incident in French aviation history.
 +
 +The wreckage was located after a long search of 10,000 sq km (3,860 sq miles) of sea floor. But the flight recorder was not found until 2011, after months of deep-sea searches.
 +
 +Relatives of some of the passengers, who were mainly French, Brazilian and German nationals, gathered to hear the verdict on Thursday.
 +
 +The companies have been asked to pay the maximum fine - €225,000 ($261,720; £194,500) each - but some victims' families have criticised the amount as a token penalty.
 +
 +Daniele Lamy, president of the AF447 victims' association, who lost her ​son in the accident, praised the court's verdict, adding that the justice system was "at last, taking into account the pain of the families faced with a collective tragedy of unbearable brutality".

 +== ‘There Was a Noise, Like a Tire Bursting’: Man Partially Sucked Out of Window on Ryanair Flight ==
 +
 +Thankfully, the passenger was wearing his seatbelt.
 +
 +Matt Novak - July 10, 2026, 1:15 pm ET
 +
 +A man was partially sucked out of a plane window on a flight from Greece to Germany on Friday after the window “detached,” according to a report from Ireland’s RTE. Passengers aboard the Ryanair flight described a loud noise, like a “tire bursting” before decompression of the cabin and masks dropping from the ceiling, the news outlet reports.
 +
 +“There were screams […] for a moment I thought someone had accidentally opened the emergency door,” one woman told RTE. “The masks dropped, and there was a strong smell; the head and shoulders of one passenger were outside the window.”
 +
 +The man was wearing his seatbelt and wasn’t completely sucked out, according to RTE, and other passengers helped pull the man back inside the cabin. The terrifying incident occurred after a piece of debris detached from one of the Boeing 737-800’s engines, a claim that has not been verified by the airline.
 +
 +The passenger is a tourist from Serbia who was traveling from Thessaloniki in Greece to Memmingen in Germany, according to France24, and the incident occurred over North Macedonia. The man has not been publicly identified but is reportedly 61 years old and was hospitalized with friction burns, but has been described as in “good condition.”

 +A graduate in German, Jake has a passion for history and regional aviation, and enjoys sampling new carriers and aircraft. He has visited OEM facilities as far and wide as Bristol, Toulouse, and Seattle, and recently enjoyed the milestone of flying his 150th sector as a passenger. Based in Norfolk, UK.
 +Here is a fact-based summary of the story contents:
 +
 +A Ryanair Boeing 737-800 flying from Thessaloniki Airport (SKG) in Greece to Memmingen Airport (FMM) in Germany had to return to its point of departure on Friday after debris from a dramatic engine failure caused damage to the aircraft's window. The incident injured one of the plane's passengers, with some reports suggesting that they were even partially sucked out of the broken window.
 +
 +Despite the dramatic turn of inflight events, the flight's pilots were able to safely land the aircraft back in Thessaloniki. Ryanair has since confirmed that the injured passenger received medical assistance upon arrival back in Greece, and the carrier also arranged a replacement aircraft in order to get the flight's other guests back on their way with as little delay as possible.

 +
 +Russian attack? Explosive drone targeted parked aircraft at Leipzig airport.
 +
 +Jeremy Hsu – Aug 6, 2026 3:01 PM
 +
 +German police disarmed a drone carrying explosives after it was discovered near Ukrainian cargo aircraft parked at Leipzig airport—and authorities are looking into the possibility of a second drone after an approaching aircraft collided with something midair.
 +
 +The drone, first spotted by an airport employee, was hovering close to the ground between two parked An-124 cargo aircraft owned by Ukraine’s Antonov Airlines shortly before midnight on August 4, according to The Guardian. It had apparently been modified to help avoid detection by the airport’s drone defense sensors, said Alexander Dobrindt, federal minister of the interior for Germany, during a press conference.
 +
 +Dobrindt described the drone as carrying a fist-sized package of a substance believed to be the plastic explosive Semtex. Only a failed detonator prevented the drone from exploding near the Ukrainian cargo aircraft, he said.
 +
 +A bus driver managed to kick the flying drone and caused it to crash, according to Detlef Seif, a lawmaker and member of the German parliament’s interior committee. In an interview with Reuters, Seif described the driver’s actions as “very daring and courageous, but also very dangerous,” while acknowledging that “it is possible that his intervention prevented the intended attack.”
 +
 +German police used a bomb disposal robot to help disarm the drone and later carried out a controlled explosion, according to BBC News.
 +
 +Contrary to some media reports, the German Interior Ministry has denied that the apparently targeted Ukrainian cargo aircraft were carrying weapons or other munitions for delivery to Ukraine, according to Deutsche Welle. Instead, government officials described the aircraft as having been empty at the time of the drone incident.

 +== LaGuardia pilots raised safety alarms months before deadly runway crash ==
 +
 +Nasa reports show repeated warnings of close calls before crash that killed two pilots and injured 41 others
 +
 +Edward Helmore - Tue 24 Mar 2026 09.33 EDT
 +
 +Pilot safety concerns about New York’s LaGuardia airport were filed to aviation officials months before Sunday’s collision between an airplane and a fire truck left two pilots dead and 41 other people hospitalized.
 +
 +According to the aviation safety reporting system administered by the US space agency Nasa, a pilot using the airport in the summer wrote, “Please do something,” after air traffic controllers failed to provide appropriate guidance about multiple nearby aircraft.
 +
 +“The pace of operations is building in LGA,” they wrote, referring to the New York City airport, one of the busiest in the US. “The controllers are pushing the line.”
 +
 +In a reference to the January 2025 mid-air collision over the Potomac River in Washington DC that killed more than 60 people, they said: “On thunderstorm days, LGA is starting to feel like [Ronald Reagan National airport] did before the accident there.”
 +
 +The warning, first reported by CNN, showed that the pilot of the aircraft was concerned that LaGuardia’s control tower initiated a takeoff clearance for an aircraft when their plane was “only 300 feet high on final” approach on a different runway – and the departing plane had hesitated initiating its takeoff run.

 +
 +Patrick Reilly - March 25, 2026, 7:17 a.m. ET
 +
 +The air traffic controller at the helm when an Air Canada plane crashed into a rescue truck at LaGuardia Airport continued working after the deadly incident.
 +
 +Only two controllers were on duty when two pilots were killed in the crash around 11:45 p.m. Sunday — but only one of them cleared the emergency vehicle to cross the runway to respond to an incident on another plane just as the Air Canada jet was landing, NTSB chairwoman Jennifer Homendy revealed.
 +
 +“We know that that controller was still on duty for several minutes afterwards. Normally, they would be relieved,” she said.
 +
 +“We have questions about that. Was anybody available to relieve that controller? We don’t know that yet.”
 +
 +Homendy warned against “pointing fingers at controllers and saying distraction was involved,” as some reports claimed the FAA was investigating.
 +
 +The potential distraction was a United Airlines flight on which a mysterious odor had sickened crew members.

 +
 +== A Civilian Plane Crashed in New Mexico. Was the Military’s Tech to Blame? ==
 +
 +Drone warfare is making the skies more dangerous, even for airplanes far from the battlefield.
 +
 +Jeff Wise - Jul 30, 2026 6:00 AM
 +
 +This past May, a twin-engine Beechcraft King Air medevac plane took off from Roswell, New Mexico, and headed west to the town of Ruidoso to pick up a patient. It shouldn’t have been a challenging flight for the two pilots and two nurses aboard. The temperature was 69 degrees; the sky was clear. The 60-mile journey normally takes a half hour, at most.
 +
 +But once airborne, the plane ran into trouble. At the White Sands Missile Range that night, US military personnel were conducting a GPS jamming exercise that left the King Air pilots—and anyone else within hundreds of miles—unable to use modern navigation systems. Forced to revert to older technology, ones that they rarely if ever use, the medevac pilots got disoriented and crashed into the side of a mountain. There were no survivors.
 +
 +The accident marked the first time that GPS jamming had contributed to the crash of a civilian plane in the United States. But it was just one of a string of recent disruptions across the world. The skies are more contested than ever, whether it’s civilian drones wandering out of the approved zone or US agencies getting their signals crossed, as happened earlier this year when New Mexico and Texas scared the public by temporarily closing their airspace. (It turned out that US Customs and Border Patrol were using anti-drone lasers in that area.) The GPS jamming exercise that led to this latest crash is not a singular event. In the past year, the US military appeared to have sent out notices for at least 10 such exercises. “As drone warfare and electronic warfare expand, airlines are increasingly encountering navigation disruptions hundreds of miles beyond the actual conflict zone,” says Eliran Almog, CEO of the cybersecurity firm Cyviation.

 +== How Much Does It Cost To Fly A Private Jet From New York To California? ==
 +
 +Patricia Green - Apr 26, 2026, 9:31 AM EDT
 +
 +Private jet travel has boomed in popularity since the pandemic, as more people found out how flexible and convenient it was. The time saved at airports is considerable, with all the processes streamlined, efficient, and personalized. Private jets are luxurious and very comfortable, as well as saving precious time. So, for high-flying business executives, celebrities, or ultra-high-net-worth individuals, flying privately offers the best experience, especially in the United States, where business jets are a firm feature.
 +
 +Private jet travel can be expensive, but how much does it cost to travel from New York to California? One of the most popular destinations for private jets is Los Angeles. So let's use that as a guideline and look at some different options. Is there a cheaper way to fly private? Is it cheaper to consider private ownership or charter with an operator on a regular basis? Let's find out!

 +
 +Dhananjay Khadilkar – Aug 7, 2026 12:00 PM
 +
 +A walk down the tarmac at the National Air and Space Museum of France is guaranteed to thrill aviation enthusiasts. Several civilian and military aircraft of the past and the present are showcased in this museum, located at the Paris-Le Bourget airport. One of them is the legendary Concorde F-WTSS 001 prototype, the sight of which should give goosebumps to science enthusiasts as well.
 +
 +That’s because right behind its long nose is a painted map that traces the path of a June 1973 total solar eclipse across Africa. It’s there on the Concorde 001 prototype because a group of eight scientists set a new world record of observing a total solar eclipse for 74 minutes by flying this aircraft at more than twice the speed of sound.
 +
 +To put this figure into context, the maximum duration of totality on the ground is around 7.5 minutes when an eclipse is observed in the equatorial regions. For the upcoming solar eclipse of August 12, which can be seen from parts of Europe, the maximum duration of totality from the ground will be slightly more than two minutes.

 +== FAA Takes First Step to Scrap the Ban on Supersonic Flights Over the U.S. ==
 +
 +Sean Duffy says new tech makes it safer for people on the ground who are worried about sonic booms.
 +
 +Matt Novak - June 30, 2026, 4:20 pm ET
 +
 +The Federal Aviation Administration announced a proposed rule change Tuesday that would lift the ban on supersonic flights over the continental U.S. by non-military planes, a policy that’s been in place since 1973.
 +
 +Planes traveling over Mach 1 typically cause sonic booms, shock waves made by planes traveling faster than the speed of sound. Sonic booms over the land can cause property damage, as they did in the 1960s when military planes would shatter windows and break dishes in the homes below.
 +
 +New technological advancements have made the 53-year-old ban obsolete, according to the FAA, and so the Trump administration wants to return over-land supersonic air travel to the U.S.. The Concorde, which flew from 1976-2003 and could travel from London to New York in just three hours, flew primarily over the Atlantic Ocean where sonic booms rarely disturbed humans living below.
 +
 +“Advances in aerospace engineering, materials science, noise reduction, and new operational concepts will eliminate the old sonic boom,” FAA Administrator Bryan Bedford said Tuesday in a statement. “This means we can ultimately repeal the ban from the 1970s on supersonic flight over U.S. territory while minimizing noise impacts to residents in communities along the route and near airports.”

 +== DOT Announces 'Return of Supersonic Flight' For Commercial Airlines ==
 +
 +Posted by BeauHD on Wednesday July 01, 2026 02:00AM
 +
 +The FAA plans to replace its 1973 ban on civilian supersonic flight over U.S. land with a noise-based standard, potentially allowing aircraft to exceed Mach 1 as long as they stay below certain sound limits. The agency aims to finalize the rules by mid-2027, opening the door for companies such as Boom Supersonic and Spike Aerospace to operate quieter next-generation passenger jets over land. Longtime Slashdot reader schwit1 shared the notice (PDF) published Tuesday by the FAA. Forbes reports:
 +
 +<blockquote>
 +Technological advances "will eliminate the old sonic boom," FAA Administrator Bryan Bedford said in a statement. "This means we can ultimately repeal the ban from the 1970s on supersonic flight over U.S. territory while minimizing noise impacts to residents in communities along the route and near airports." The primary reason was public opposition to loud sonic booms. In the 1960s, a plane flying faster than the speed of sound -- about 660 mph at high altitudes -- created shock waves that traveled to the ground and reached human ears as a loud gunshot-like crack or thunder-like boom. Tests during that decade, including the Oklahoma City sonic boom experiments, found repeated booms broke windows, damaged property and generated thousands of public complaints.

 +== FAA proposal: Supersonic airliners can fly over US cities if they’re quiet ==
 +
 +New US rules would legalize quiet supersonic flights without the sonic boom.
 +
 +Jeremy Hsu – Jul 2, 2026 10:29 AM
 +
 +A long-standing ban on commercial supersonic flights over the United States would be overturned in a new rule proposed by the US Federal Aviation Administration. That could pave the way for the possible return of commercial supersonic airliners—as long as such aircraft can reduce the ground-level impacts of their sonic booms.
 +
 +The FAA originally banned overland supersonic flights by civil aircraft in 1973, following US military tests involving supersonic flights over US cities such as Oklahoma City, Chicago, and St. Louis in the 1960s. But the Trump administration has championed the repeal of the ban to pave the way for supersonic airliners that could operate without disruptive sonic booms. So the FAA’s new rulemaking action on June 30, 2026, follows the direction of an executive order issued by President Trump on June 6, 2025.
 +
 +The newly proposed rule would replace the 53-year prohibition with an interim “noise-based” certification standard requiring any sonic boom overpressure at the surface to be kept below 0.11 pounds per square foot. That proposed standard is based on the Colorado-based startup Boom Supersonic having demonstrated quiet Mach cutoff flights with its XB-1 aircraft—harnessing specific atmospheric conditions while flying just beyond supersonic speeds at higher altitudes so that the aircraft’s shockwaves are refracted upward into the atmosphere rather than traveling to the ground.
 +
 +For comparison, the Concorde supersonic airliner that flew commercial transatlantic flights between 1976 and 2003 created a sonic boom overpressure equivalent to 1.94 pounds per square foot when flying at a speed of Mach 2 at an altitude of 52,000 feet.
 +
 +A NASA fact sheet suggests that “some public reaction could be expected between 1.5 and 2 pounds” but rules out damage to buildings and other structures at one pound of overpressure. It further explains that humans have experienced sonic boom overpressure between 20 and 144 pounds without injury when supersonic aircraft flew at altitudes below 100 feet.
