Question: London (CNN) -- London's Heathrow Airport is "fully operational" and returning to normal after an emergency landing Friday forced the closing of both runways, the airport said -- but many travelers are likely to suffer delays anyway. British Airways has canceled all its inbound and outbound short-haul flights until 4 p.m. (11 a.m. ET) as a result of the incident. And Heathrow Airport has warned of disruption to travel that could last all day. So far, 23 planes have been diverted to other airports and 19 flights canceled, some arrivals and some departures, a spokeswoman said Friday morning. The airport is working to return to normal service as soon as possible, she said, but passengers are advised to check with their airlines. A British Airways plane bound for Oslo was forced to make the emergency landing "due to a technical fault," the airline said. Flight BA762 turned back less than half an hour after taking off for the Norwegian capital, it said. The Airbus A319 aircraft was carrying 75 passengers and five crew members, the airline said. The passengers were evacuated from the plane on emergency slides. "Airline colleagues are now caring for customers in the airport terminal," said British Airways. London Ambulance Service treated three patients for minor injuries after the emergency landing, it said on Twitter. British Airways said it would be carrying out a full investigation into the incident, alongside the Air Accident Investigation Branch, part of the UK Department for Transport. The slides were deployed on the left side of the aircraft, indicating that the problem was with the right engine, said CNN's Richard Quest. Planes can fly safely even if only one engine is operational, he said. London Fire Brigade said one of its crews helped the airport fire service put out an aircraft fire. "We believe the fire is now out," it said via Twitter. Heathrow, which is a major international hub, was ranked the third busiest airport in the world in 2012 after Atlanta and Beijing, according to Airports Council International. Monday is a holiday in the United Kingdom, so many people will be taking flights Friday to take advantage of the long weekend. Holidaymaker Aileen Wilson was one of many travelers whose flight was grounded by the incident. "We've just been sitting, waiting in a plane meant to take off" this morning, she told CNN iReport. "At first we were told ongoing incident and then emergency landing. We (are) still waiting to take off (and) not allowed out of plane!" Instagram user Shazia Shaikh took a photograph from the office where she works at Heathrow Airport of emergency vehicles surrounding a plane. "Runways closed (and) lots of smoke," she told CNN iReport. "The rain doesn't help. Emergency vehicles were quick to the aircraft I'm told." On average, 190,000 passengers travel through the airport each day, half arriving and half departing, according to Heathrow's website. CNN's Claudia Rebaza, Richard Allen Greene, Sarah Brown and Dominique Van Heerden contributed to this report.

Question: (CNN) -- Even a presidential campaign's airplane troubles can get partisan in an election year. Aviation incidents involving President Barack Obama and Ann Romney, wife of Republican presidential candidate Mitt Romney, have inspired hundreds of supporters commenting at CNN.com to connect those events to the candidates' political positions. When the Air Force One pilot aborted his first landing in Toledo, Ohio, due to weather on Wednesday, commenters were quick to jump on Obama. "See, Barack Obama can't even land a plane correctly," wrote a commenter whose handle is TheOtherBob. "He was probably checking the polls - thinks he has Ohio in the bag - no need to land," wrote another commenter. "He was distracted, since he was busy adjusting gas prices over his smart phone," wrote another commenter. Ann Romney's smoke-filled plane . Ann Romney couldn't catch a break, either. Her airplane cabin filling up with smoke due to an electrical problem was no laughing matter, but commenters quickly took aim at her husband and his response. Mitt Romney talked about not being able to open the airplane's windows in flight. (New York Times writer Ashley Parker, who wrote the presidential pool report mentioning the comments, declined to comment on his remarks, referring CNN to a New York magazine piece where she made it clear that Romney was joking.) "Maybe if Romney hadn't started the outsourcing trend, that plane would have been built and maintained better by hardworking 47%ers," wrote one commenter. "Firefighters came to the rescue, paramedics were there on time and the police took special care of your security. We are the 47% your husband scorns," wrote commenter Kweso. Reminders of the actual flying conditions . Enough with the political bickering, suggested some commenters. "The hate thrown out at the Romneys (and at President Obama) is just plain absurd," wrote commenter jolivier23. On Romney's flight: "CAN YOU PEOPLE STOP WITH THIS CHARADE. Can you just be happy that the everyone was safe and no one was injured," wrote one commenter. "What is wrong with you people? Why are you making this a political issue? I am just glad nobody was hurt. " On Obama's flight: "This incident with the President was just routine turbulence which is something that you really can't do anything about in the first place," wrote one commenter. "If the one of the best pilots (and co-pilots) in the U.S. Air Force aborts a landing you know the conditions were hairy," wrote daehttub2000. Perhaps remembering a line from that esteemed television show "Hill Street Blues," he wrote, "Let's be careful out there." Many of us have stories of grabbing a complete stranger or picking airline pretzels out of our hair after a particularly bad bout of turbulence. Do you have any stories to share?

Question: (CNN) -- Usain Bolt rounded off the world championships Sunday by claiming his third gold in Moscow as he anchored Jamaica to victory in the men's 4x100m relay. The fastest man in the world charged clear of United States rival Justin Gatlin as the Jamaican quartet of Nesta Carter, Kemar Bailey-Cole, Nickel Ashmeade and Bolt won in 37.36 seconds. The U.S finished second in 37.56 seconds with Canada taking the bronze after Britain were disqualified for a faulty handover. The 26-year-old Bolt has now collected eight gold medals at world championships, equaling the record held by American trio Carl Lewis, Michael Johnson and Allyson Felix, not to mention the small matter of six Olympic titles. The relay triumph followed individual successes in the 100 and 200 meters in the Russian capital. "I'm proud of myself and I'll continue to work to dominate for as long as possible," Bolt said, having previously expressed his intention to carry on until the 2016 Rio Olympics. Victory was never seriously in doubt once he got the baton safely in hand from Ashmeade, while Gatlin and the United States third leg runner Rakieem Salaam had problems. Gatlin strayed out of his lane as he struggled to get full control of their baton and was never able to get on terms with Bolt. Earlier, Jamaica's women underlined their dominance in the sprint events by winning the 4x100m relay gold, anchored by Shelly-Ann Fraser-Pryce, who like Bolt was completing a triple. Their quartet recorded a championship record of 41.29 seconds, well clear of France, who crossed the line in second place in 42.73 seconds. Defending champions, the United States, were initially back in the bronze medal position after losing time on the second handover between Alexandria Anderson and English Gardner, but promoted to silver when France were subsequently disqualified for an illegal handover. The British quartet, who were initially fourth, were promoted to the bronze which eluded their men's team. Fraser-Pryce, like Bolt aged 26, became the first woman to achieve three golds in the 100-200 and the relay. In other final action on the last day of the championships, France's Teddy Tamgho became the third man to leap over 18m in the triple jump, exceeding the mark by four centimeters to take gold. Germany's Christina Obergfoll finally took gold at global level in the women's javelin after five previous silvers, while Kenya's Asbel Kiprop easily won a tactical men's 1500m final. Kiprop's compatriot Eunice Jepkoech Sum was a surprise winner of the women's 800m. Bolt's final dash for golden glory brought the eight-day championship to a rousing finale, but while the hosts topped the medal table from the United States there was criticism of the poor attendances in the Luzhniki Stadium. There was further concern when their pole vault gold medalist Yelena Isinbayeva made controversial remarks in support of Russia's new laws, which make "the propagandizing of non-traditional sexual relations among minors" a criminal offense. She later attempted to clarify her comments, but there were renewed calls by gay rights groups for a boycott of the 2014 Winter Games in Sochi, the next major sports event in Russia.
