Two planes almost collided at New York's LaGuardia Airport. Here's what happened.
Federal investigators are looking into a close call at New York's LaGuardia Airport earlier this month, where two planes nearly collided on a runway despite the airport being equipped with an advanced ground radar system designed to prevent such incidents.
The Federal Aviation Administration (FAA) and the National Transportation Safety Board (NTSB) confirmed on Monday that they are investigating the May 6 incident, in which a Republic Airways jet was forced to abort takeoff because a United Airlines plane was still taxiing across the runway.
Audio obtained by ABC News from LiveATC.net captured a controller telling the Republic pilot: 'Sorry, I thought United had cleared well before that.'
At the time, one controller had cleared the Republic jet for takeoff while another, on a different radio frequency, was redirecting the United plane after it missed its designated taxiway exit.
United Airlines did not immediately respond to inquiries, while Republic Airways and airport officials deferred questions to the FAA.

The incident adds to growing concerns over
runway safety
. The number of near collisions has remained steady over the past decade, with roughly 30 incursions per million takeoffs and landings. While most are minor, 2023 saw 22 serious runway incursions—those with high collision risk—though that number dropped to seven last year, according to FAA data.
LaGuardia is among just 35 U.S. airports equipped with the FAA's top-tier surface surveillance system, ASDE-X, which tracks aircraft and vehicles on the ground. The other 490 control-towered airports rely on visual tracking methods, such as binoculars, due to the high cost of the technology.
Transportation Secretary Sean Duffy has proposed expanding ASDE-X and similar systems nationwide as part of a broader modernization plan, but it requires Congressional approval.
Still, the recent LaGuardia incident shows the limitations of even the most advanced systems. The FAA plans to install an additional warning system at the airport and is exploring technologies that would alert pilots directly of runway hazards, rather than relying solely on air traffic controllers. A system under development by Honeywell has yet to receive FAA certification.
The ongoing focus on runway safety stems in part from historical tragedies, including the deadliest aviation accident on record—a 1977 runway collision in Tenerife, Spain, that killed 583 people.

Boeing Dreamliner has history of technical issues globally
New Delhi: The Boeing 787-8 Dreamliner, known for its advanced technology and fuel efficiency, has reportedly faced several technical and safety issues worldwide over the years. In 2013, the entire global fleet of Dreamliners was grounded after incidents of lithium-ion battery fires, including one on a parked Japan Airlines jet in Boston and another mid-air emergency in Japan. These incidents led the US Federal Aviation Administration (FAA) to suspend Dreamliner operations until Boeing redesigned the battery system. In 2024, Boeing again came under scrutiny after whistleblower Sam Salehpour, an engineer at the company, reportedly told the US Senate about structural problems in the Dreamliner's fuselage. He claimed that small gaps and improper assembly could cause early wear and possible structural failure. The FAA launched an investigation, which is still ongoing. Despite being marketed as one of the safest and most advanced aircraft in the skies, the Dreamliner has been linked to several technical faults. In March this year, a Boeing 787-9, operated by LATAM Airlines, experienced a sudden altitude drop mid-flight, injuring 50 people. The cause was later identified as a malfunction in the cockpit seat. Over the years, pilots have also reported issues such as engine icing, fuel leaks, generator failures, and electrical system faults.

Air India plane 787 Dreamliner's first crash clouds Boeing's Paris air show
Mumbai: The Air India plane disaster on Thursday in Ahmedabad is the first time a Boeing 787 Dreamliner has crashed since the model's introduction in 2011. On 30 April, the American aircraft manufacturer highlighted the success of the Dreamliner series in a press release, noting that its 1,175 planes had carried 1 billion passengers in 14 years, a record that surpasses any other wide-body commercial aeroplane in history. 'Flying over 1 billion passengers in this relatively short time is a testament to how the airplane has delivered on its promises to transform air travel with operational versatility, efficiency and comfort," said Scott Stocker, Boeing 787 program vice-president and general manager. Airlines using the Dreamliner series have praised the planes for their significantly improved fuel efficiency. The 787 family is 25% more fuel-efficient than the aeroplanes it replaces, thanks in large part to new engines, the expanded use of lightweight composite materials, more efficient system applications, and modern aerodynamics, Boeing said in a statement dated 30 April. To be sure, Boeing 787 Dreamliner planes have experienced operational problems in the past. These planes faced significant battery issues in 2013, leading to a worldwide grounding of the fleet. These problems stemmed from lithium-ion batteries used in the aircraft's auxiliary power unit (APU), which were prone to thermal runaway and fires. The issues ultimately resulted in the grounding of the Dreamliner fleet, with the US Federal Aviation Administration (FAA) and National Transportation Safety Board (NTSB) investigating the design and manufacturing of the batteries. Also read How the crash impacts Air India, insurers and Boeing Air India had also grounded its planes and subsequently made the necessary changes before flying them again. The aircraft has had no issues since then. However, Thursday's crash is the first crash reported in the Boeing 787 Dreamliner series, according to the Aviation Safety Network database. In April 2024, the FAA announced that it was investigating claims made by a Boeing engineer who alleged that parts of the 787 Dreamliner's fuselage were improperly fastened together. Worryingly, the engineer had told the aviation regulator that the fuselage could break apart mid-flight. Boeing rejected the claims by the former engineer. Aviation consultant John M. Cox, the CEO of Safety Operating Systems, told the Associated Press that while the initial images of Thursday's crash were poor, they appeared to show the aircraft with its nose up and not climbing, which is one of the factors investigators would examine. 'At this point, it's very, very, very early, we don't know a whole lot," Cox told AP. 'But the 787 has very extensive flight data monitoring--the parameters on the flight data recorder are in the thousands--so once we get that recorder, they'll be able to know pretty quickly what happened." Thursday's crash comes after Boeing last month agreed to pay $1.1 billion in a deal with the US Department of Justice to avoid prosecution over the two crashes that together killed 346 people. The two major crashes that resulted from faults in Boeing planes, specifically the 737 Max model, occurred in Indonesia and Ethiopia in 2018 and 2019. The Boeing 737 Max model was grounded for almost a year before being relaunched. For Boeing, the latest crash is bad news coming just a week ahead of the Paris Air Show, where it could have booked fresh orders. Its shares were trading nearly 6% lower in pre-market deals on Thursday. Read this Air India's Boeing Dreamliner crashes minutes after takeoff 'With profound sorrow I confirm that Air India flight, AI 171 operating Ahmedabad London Gatwick was involved in a tragic accident today," Natarajan Chandrasekaran, Tata Sons chairman, said in a prepared statement. Chandrasekaran, who is also the chair of Air India, added: 'At this moment, our primary focus is on supporting all the affected people and their families. We are doing everything in our power to assist the emergency response teams at the site and to provide all necessary support and care to those impacted." "We are deeply saddened by the tragic accident involving Air India Flight 171 on its journey from Ahmedabad to London. This heart-wrenching incident has brought immense grief to countless families, and our thoughts are with all those who have lost their loved ones today," said Noel Tata, chair of Tata Trusts, the philanthropic entities that control the Tata conglomerate. In a statement reacting to the crash, Boeing said: 'We are aware of initial reports and are working to gather more information." "The FAA (Federal Aviation Administration) is in contact with the NTSB (National Transportation Safety Board) regarding Air India flight AI171, operating from Ahmedabad (AMD) to London Gatwick (LGW), that was involved in an accident in India on Thursday, June 12," FAA said in a statement on Thursday. "When an international incident occurs, that government leads the investigation. In the event assistance is requested, the NTSB is the official U.S. representative and the FAA provides technical support. We stand ready to launch a team immediately in coordination with the NTSB". For now, there is no certainty whether India's civil aviation watchdog Directorate General of Civil Aviation (DGCA) will ground the rest of the Dreamliners aircraft. And read Will the Air India crash lead to the grounding of the Dreamliner series and disrupt travel? 'This is a very successful aircraft, this is probably the first major issue with the 787, it will not affect the company's prospects. The DGCA will not ground the rest of the fleet, if they do, it would be a thoughtless act," said Captain Mohan Ranganathan, a former airline instructor pilot. As of 14 April 2025, Air India's fleet comprises 198 aircraft. This includes 34 Dreamliners, comprising 27 Boeing 787-8s and 7 Boeing 787-9s. Boeing has a robust order book for the Dreamliner, including 20 from Air India, the first of which is due by the end of this year.

Ahmedabad plane crash: History of the Boeing 787 Dreamliner, past safety concerns around it
A London-bound Air India flight crashed moments after takeoff near the Sardar Vallabhbhai Patel International Airport in Ahmedabad on Thursday afternoon (June 12). As many as 242 people were on board, including two pilots and crew members. The AI171 flight was en route to the London Gatwick Airport and took off at 1.39 pm from Runway 23 of the Ahmedabad airport. The pilot issued a mayday call to the Air Traffic Controller (ATC) shortly after takeoff. The aircraft reached just 625 feet before plummeting into a nearby residential area. The cause of the crash was not immediately known. According to Air India, the crashed plane was a Boeing 787-8 Dreamliner, considered to be one of the most advanced passenger aircraft. This is the first fatal incident involving the Boeing 787s, but not its first brush with safety issues. Boeing has said it was aware of initial reports and was working to gather more information. Here's what we know about Boeing 787. The aircraft involved in Thursday's crash entered Air India's fleet in 2014. Boeing introduced the 787 in 2007 as a next-generation, fuel-efficient long-haul jet. Its first test flight took place in December 2009. However, the path to commercial service was dogged by global supply chain issues, in-flight software bugs, and engine troubles that delayed its launch. The first commercial Boeing 787 took flight in 2012. The Dreamliner is a wide-body jet designed for long-haul efficiency. Crucially, the lighter structure of the aircraft allows it to use 25 per cent less fuel than previously designed airplanes. Boeing has called the 787 Dreamliner as its 'best selling passenger planes' as it offers spacious cabins and large windows, along with a comfortable cockpit. It has three variants: the 787-8, 7887-9 and the 787-10. AI171 was the 787-8 variant, which can carry up to 248 passengers and cover a distance of 13,530 km. It is 57 metres long and has a wingspan of 60 metres. It is equipped with the GEnx-1B/Trent 1000 engine. Over the years, however, concerns have been raised around the safety of Boeing 787s, but the airline company has remained confident in the aircraft's design. The aircraft manufacturer is facing several US Federal Aviation Administration (FAA) investigations over safety concerns. In May 2024, the FAA announced that Boeing was 'reinspecting all 787 airplanes still within the production system' and would make plans to assess those in service. A month prior to it, the FAA launched an investigation into alarming claims by whistleblower Sam Salehpour, a former Boeing engineer. He alleged that sections of the fuselage of the 787 Dreamliner were improperly fastened together. He had warned that the plane could come apart after long-term usage. Boeing had dismissed the claims, calling them 'inaccurate'. A company spokesman told The New York Times that Salehpour's claims 'do not represent the comprehensive work Boeing has done to ensure the quality and long-term safety of the aircraft'. In March 2024, another Boeing whistleblower, John Barnett, was found dead from a suspected 'self-inflicted' gunshot wound. A longtime employee, Barnett had worked at a 787 manufacturing facility in South Carolina. Back in 2019, he accused Boeing of installing substandard parts in the Dreamliners to speed up production. Boeing has denied the claims. The Dreamliner has also been linked to other flight safety scares. In March 2024, a Latam Airlines 787 en route to New Zealand suddenly plunged mid-flight before the pilot regained control. A Wall Street Journal report later traced the incident to human error. Back in 2013, flight safety regulators across the world, including India, grounded the entire fleet of Boeing 787 Dreamliners. At the time, Air India (then government-owned) owned six 787s. The move came after the FAA raised red flags about the aircraft's lithium-ion batteries. Apart from the Dreamliners, Boeing has been facing increased scrutiny over the safety of its jets ever since two fatal crashes of its 737 Max plane in 2018 and 2019.
