A spokesperson said United flight 433, from San Francisco, arrived at the Rogue Valley International Airport in Medford, Oregon, at about 11:30 (18:30 GMT) on Friday.The 25-year-old Boeing 737-800 was carrying 139 passengers and 6 crew.No-one was injured – the missing panel went unnoticed during the flight.Boeing is under fierce scrutiny after a series of high-profile safety incidents.Amber Judd, a senior official at Rogue Valley International Medford Airport, said the plane landed safely and the external panel was only discovered missing during a post-flight inspection.”We’ll conduct a thorough examination of the plane and perform all the needed repairs before it returns to service,” she said.An investigation would be carried out “to better better understand how this damage occurred”, she added.The missing panel was next to the landing gear, on the underside of the aircraft, according to images of the aircraft on social media. All outgoing and incoming flights were paused at the airport to search for debris, none was found. The US Federal Aviation Authority (FAA) said it was investigating how the panel came apart.Boeing came under renewed scrutiny after a January incident involving a Boeing 737 Max 9 – part of a new range of planes to succeed older 737s – saw an unused cabin door blow out a few minutes after take-off in January.The incident onboard Alaska Airlines flight 1282 left a gaping hole in the side of the plane and forced an emergency landing.Image source, National Transportation Safety BoardImage caption, A safety board investigator examines the broken panel two days after the incident in JanuaryTestifying before US lawmakers on 7 February after the Alaska Airlines blowout incident, the head of the FAA, Mike Whitaker, said inspections of 737 Max aircraft had shown that “the quality system issues at Boeing were unacceptable and require further scrutiny”.Initial findings of a probe found that four key bolts that were meant to lock the unused door to the fuselage appeared to be missing. Mr Whitaker said that Boeing would be held accountable for any future failure or refusal to comply with the FAA. Earlier this month, fumes detected in the cabin of an Alaska Airlines Boeing 737-800 bound for Phoenix forced pilots to return to Portland airport.Fifty hurt as jet to NZ hit by ‘technical’ issueBoeing whistleblower found dead in USBoeing 737 Max boss out after blowoutOn Monday, at least 50 people were injured after a Boeing 787-9 Dreamliner flying from Australia to New Zealand suddenly dropped without warning, leaving passengers who were not wearing seatbelts tossed into aisles and flung into the ceiling.In response to that incident, Boeing has told airlines that pilots need to check their seats – after reports said a flight attendant accidentally hit a switch in the cockpit which pushed the pilot’s seat forward into the controls – forcing the plane’s nose down.Despite the reported incidents, commercial aviation remains one of the safest ways to travel, experts and regulators say.Flight 1282: The BlowoutEvery passenger’s worst nightmare: the terrifying moment a plane door rips away mid-air.Watch now on BBC iPlayer (UK Only)Related TopicsOregonAviation accidents and incidentsBoeingAviation safetySan FranciscoAir travelMore on this storyBoeing tells pilots to check seats after plane dropsPublished18 hours agoBoeing whistleblower found dead in USPublished4 days agoKey questions behind plane’s mid-air blowoutPublished9 JanuaryTop StoriesVaughan Gething set to be Wales’ next first ministerPublished15 minutes agoSainsbury’s deliveries cancelled due to tech issuesPublished18 minutes agoDrivers disrupted as M25 closures cause delaysPublished4 minutes agoFeaturesThe ‘insane’ plan to save the Arctic’s sea-iceThe Papers: ‘Tory PM ousting plot’ and ‘Gran’s death row wait’Ros Atkins on… Why one in five people do not work.

To slow global warming.As sea-ice vanishes, the dark ocean surface can absorb more of the Sun’s energy, which accelerates warming. So the researchers want to thicken it to stop it melting away.Welcome to the wackier side of geoengineering – deliberately intervening in the Earth’s climate system to try to counteract the damage we have done to it.Polar bears face starvation as ice meltsMore snow and rain is falling in the ArcticHottest February marks ninth new monthly record in a rowGeoengineering includes more established efforts to lock up planet-warming gases, such as planting more trees and burying carbon underground.But more experimental measures aim to go a step further, seeking to reduce the energy absorbed by the Earth.Many scientists are strongly opposed, warning that such attempts distract from the critical step of cutting carbon emissions and risk doing more harm than good.But a small number of advocates claim their approaches could give the planet a helping hand while humanity cleans up its act.The ultimate goal of the Arctic experiment is to thicken enough sea-ice to slow or even reverse the melting already seen, says Dr Shaun Fitzgerald, whose team at the University of Cambridge’s Centre for Climate Repair is behind the project.Will it work or is it, as one scientist put it, “quite insane”?”We don’t actually know enough to determine whether this is a good idea or bad idea,” admits Dr Fitzgerald.Image source, Real IceImage caption, “It’s quite cold,” the researchers say. Wind chill in Cambridge Bay can make it feel like -45CThe researchers have been braving bitter conditions in Cambridge Bay, a tiny Canadian village in the Arctic Circle.”It’s quite cold,” Andrea Ceccolini of Real Ice, a British company leading the trip, tells me via a patchy Zoom connection from inside a flapping white tent.”It’s about -30C with a strong wind, which brings the temperature to -45C with wind chill factor.”They are drilling a hole in the sea-ice that naturally forms in winter, and pumping around 1,000 litres of seawater per minute across the surface. Exposed to the cold winter air, this seawater quickly freezes, helping to thicken the ice on top. The water also compacts the snow. As fresh snow acts as a good insulating layer, now ice can also form more easily on the underside in contact with the ocean.”The idea is that the thicker the ice [at the end of winter], the longer it will survive when we go into the melt season,” Mr Ceccolini explains.Image source, Real IceImage caption, A pump is used to flood the sea-ice surface with seawater, which will then freezeSpeaking to me towards the end of their trip, they’ve already seen the ice thicken by a few tens of centimetres across their small study area. The ice will be monitored by locals in the months ahead.But it’s still far too early to say whether their approach can actually make a difference to the rapid decline in Arctic sea-ice.”The vast majority of polar scientists think this is never going to work out,” cautions Martin Siegert, an experienced glaciologist at the University of Exeter, who is not involved in the project.One issue is that the saltier ice may melt more quickly in the summer. And then there’s the huge logistical challenge of scaling the project up to a meaningful level – one estimate suggests that you could need about 10 million wind-powered pumps to thicken sea-ice across just a tenth of the Arctic. “It is quite insane in my opinion that this could be done at scale for the entire Arctic Ocean,” says Julienne Stroeve, a professor of polar observation and modelling at University College London.Some of the more experimental geoengineering suggestions include trying to make clouds more reflective by generating extra sea spray, and mimicking volcanic eruptions to reflect more of the Sun’s energy back into space.A number of scientists – including the UN’s climate and weather bodies – have warned that these approaches could pose grave risks, including disrupting global weather patterns. Many researchers want to see them banned altogether. “Geoengineering technologies come with enormous uncertainties and create novel risks for ecosystems and people,” explains Lili Fuhr, director of the Fossil Economy Program at the Center for International Environmental Law.”The Arctic is essential to sustaining our planetary systems: pumping sea water onto sea-ice on a large scale could change ocean chemistry and threatens the fragile web of life.”And there’s a more fundamental, widespread concern with these types of projects.”The real danger is it provides a distraction, and people with vested interests will use it as an excuse to keep burning fossil fuels,” Prof Siegert warns.”Frankly, it’s insane and needs to be stopped. The way to solve this crisis is to decarbonise: it’s our best and only way forward.”A simple guide to climate changeWhat is net zero, and how are the UK and other countries doing?The Arctic researchers are acutely aware of these concerns. They stress that they are simply testing the technology, and wouldn’t unleash it more widely until the risks are better known.”We’re not here promoting this as the solution to climate change in the Arctic,” Dr Fitzgerald stresses. “We’re saying that it could be [part of it], but we’ve got to go and find out a lot more before society can then decide whether it’s a sensible thing or not.”They agree that geoengineering is no silver bullet to tackling climate change, and that steep cuts to fossil fuels and carbon emissions are most important to avoid the worst consequences of warming.But they point out that even with rapid action, the world still faces a difficult future.The Arctic Ocean is likely to be effectively free of sea-ice by the end of summer at least once by 2050, and possibly even sooner. As the graph below shows, it’s already experienced steep declines since the 1980s.”We need other solutions,” argues PhD student Jacob Pantling, a researcher at the Centre for Climate Repair who braved the icy winds in Cambridge Bay. “We have to reduce emissions, but even if we do them as quickly as possible, the Arctic is still going to melt.”Map by Erwan RivaultRelated TopicsArcticClimateMore on this storyPolar bears face starvation threat as ice meltsPublished13 FebruaryMore snow and rain is falling in the ArcticPublished14 December 2022Hottest February marks ninth new monthly recordPublished7 MarchWhy is the world getting warmer?Published8 FebruaryTop StoriesAid reaches shore in Gaza after first sea deliveryPublished3 hours agoAll 35 bodies in Hull funeral inquiry identifiedPublished7 hours agoRussian arrests as ballot boxes targeted in Putin votePublished7 hours agoFeatures’Tory PM ousting plot’ and ‘Gran’s death row wait’Trying to stay alive in a town tormented by drugs, alcohol and suicideFive Champions League match-ups to look forward toAttributionSportWeekly quiz: Which exclusive Oscars club did Emma Stone join?Battle between West Bank farmers divides Israel and US Listen: Putin’s Russia: An election without democracy?
