Q: A Texas company says it has made the first metal gun using a 3-D printer, taking the debate over people's emerging ability to create their own firearms to a new level. Solid Concepts, a specialty manufacturing company, said in a blog post it has fired more than 50 rounds from the handgun, even hitting a few bull's-eyes at more than 30 yards. The pistol is a version of an M1911, a handgun designed by John Browning and first used widely in the latter stages of combat stemming from the Philippine-American War. It's built from 33 mostly stainless-steel parts and has a carbon-fiber handgrip carved with a laser. "The 3-D-printed metal gun proves that 3-D printing isn't just making trinkets and Yoda heads," the company said in the blog post. Solid Concepts went out of its way Friday to point out that producing the metal gun isn't meant to advance a trend that worries law enforcement and some politicians. As 3-D printers become more widespread and affordable, some envision a near future in which criminals can crank out untraceable weapons without having to leave their homes. "Let me start out by saying one, very important thing: This is not about desktop 3-D printers," Alyssa Parkinson, a spokeswoman for the company, wrote in the blog post. The metal gun wasn't a move toward making firearms with a 3-D printer cheaper or more accessible, she wrote. Basic 3-D printers, such as the MakerBot Replicator 2, can be bought for around $2,000. But Solid Concepts used a specialized, high-end printer whose cost would be out of reach of most people. "The industrial printer we used costs more than my college tuition (and I went to a private university)," Parkinson said. "And the engineers who run our machines are top of the line; they are experts who know what they're doing and understand 3-D printing better than anyone in this business." Solid Concepts wanted to show that 3-D printing is more than just hobbyists churning out plastic doodads -- it's a viable option for serious commercial use. "It's a common misconception that 3-D printing isn't accurate or strong enough, and we're working to change people's perspectives," Kent Firestone, a vice president at the company, said in a statement. In May, a nonprofit group, also from Texas, stirred far more controversy when it posted a video of the live firing of a plastic handgun created with a 3-D printer. Cody Wilson, a 25-year-old self-described anarchist, posted instructions on how to make the gun online through his nonprofit group, Defense Distributed. Those instructions were taken down after the U.S. State Department sent the group a cease-and-desist letter. The group's website was shut down shortly afterward. Solid Concepts is a licensed firearm manufacturer. It said one use for its new capabilities with 3-D printers may be selling replacement parts for handguns.

Q: 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.

Q: Few question that there was a major chemical attack in Syria last week, and the United States has made clear that it blames the government of President Bashar al-Assad. Now, the question is how President Barack Obama will respond. For almost two years, Obama has avoided direct military involvement in Syria's civil war, only escalating aid to rebel fighters in June after suspected smaller-scale chemical weapons attacks by Syrian government forces. However, last week's attack on a Damascus suburb that reportedly killed and wounded more than 3,000 people obliterated the "red line" Obama set just over a year ago against the use of Syria's chemical weapons stocks. At the White House, spokesman Jay Carney told reporters Monday that Obama was evaluating "a response to the clear use on a mass scale with repugnant results of chemical weapons," adding that "there is very little doubt that the Syrian regime ... used those weapons." Meanwhile, U.S. Secretary of State John Kerry called the attack "inexcusable" and "undeniable," and said there was "a clear reason that the world has banned entirely chemical weapons." He said that evidence "strongly indicates" chemical weapons were used in Syria and that "we know the Syrian regime maintains custody" of such weapons and has the rockets to use them. Read Kerry's remarks . Obama "will be making an informed decision about how to respond to this indiscriminate use" of chemical weapons, Kerry added, saying the president "believes there must be accountability" for those who use them. Options available to Obama range from ordering limited missile strikes to continued diplomatic efforts labeled by critics as a "do-nothing" approach. Obama will be presented with final options regarding actions against Syria in the next few days, a senior administration official said Monday. Assuming the president decides to go ahead with a military response, any action could come as early as mid-week, though it could be later, the official cautioned. Factors weighing into the timing of any action include a desire to get it done before the president leaves for Russia next week and before the administration has to make a decision on whether to suspend aid to Egypt because of the ongoing political turmoil there, the official explained. The administration also wants it to be a quick response to the use of chemical weapons, the senior administration official said. American officials are consulting with allies to ensure they are supportive of any U.S. action, which the senior administration official said would be very limited in scope and a direct reaction to the use of chemical weapons. And three representatives of allied governments involved in those top-level consultations said the goal is to reach a consensus as soon as possible. "No one is talking about a long process," one European diplomat told CNN. Marie Harf, a State Department spokeswoman, said any U.S. response would be "a determination on how to respond to a blatant use of chemical weapons, and it's not necessarily to change the entire situation on the ground in Syria." That might be a mistake, said Michael Doran, an analyst at the Brookings Institution's Saban Center for  Middle East Policy. A U.S. strike "can't just be one and done," but should be part of a plan to remove al-Assad, he told CNN's "Anderson Cooper 360." "The president has been very reulctant to get involved. Public opinion has been against it. There's not a lot of support on the Hill," Doran said. "And yet, here we are again. Time and time again, we get dragged further and further in." The result could be "a Vietnam-type problem, where we kind of back our way into this, if we don't come up with a plan about how to win." Kerry spoke with his British, Jordanian, Qatari and Saudi counterparts Monday and with the secretary-general of the Arab League, Harf said. "Obviously, the intelligence assessment is ongoing," she said. "But he reiterated that the president is studying the facts and will be making an informed decision about how to respond going forward." The Obama administration is expected to declassify the intelligence assessment backing up its assertion that the Syrian regime was responsible for last week's chemical weapons attack, another senior administration official said. The declassification would happen before any U.S. military action would take place. A senior administration official familiar with the intelligence told CNN that the evidence "includes but is not limited to" satellite images of activity at Syrian military installations identified as including chemical weapons depots. Earlier Monday, a White House official ruled out sending ground troops to Syria or implementing a no-fly zone to blunt al-Assad's aerial superiority over rebels fighting to oust his regime. The official insisted that all other options were under consideration by Obama but put no time frame on a decision. Meanwhile, a senior Defense Department official told CNN's Chris Lawrence Monday that four U.S. Navy destroyers "maintain readiness and, if required, could execute a mission within hours" of being ordered to do so. But the official added that the U.S. military remained "in a holding pattern" as Obama considers both military and nonmilitary options. Opinion: How Al-Assad used chemical weapons to poison debate on Syria . Also, Defense Secretary Chuck Hagel said while visiting Indonesia that any U.S. action "will be in concert with the international community and within the framework of legal justification." While U.N. Secretary-General Ban Ki-moon said Monday that the use of chemical weapons was a crime against humanity and must be punished, certain opposition by Syrian ally Russia and possibly China undermined the possibility that the Security Council would support a military mission. Instead, a limited coalition of NATO partners such as Germany, France and Britain -- all of which have called for action against Syria -- and some Arab League members appeared more likely to provide the political backing needed by Obama to order U.S. missile strikes. A senior administration official told CNN on Monday that the goals of any coalition military action would be to punish al-Assad and show him that there was a cost for using chemical weapons while preventing him from doing so again. In addition, a military strike would seek to degrade the Syrian regime's capabilities enough to weaken it without causing it to fall to an opposition considered unprepared to assume power, the official said. Possible coalition partners include NATO allies Britain, France, Germany and Canada, as well as regional powers Qatar, Turkey, Saudi Arabia and the United Arab Emirates. Last month, Joint Chiefs Chairman Gen. Martin Dempsey provided Congress with a list of declassified U.S. military options for Syria that emphasized the high costs and risks of what he said would amount to "an act of war" at a time of deep budget cuts. U.S. official: Almost no doubt al-Assad regime used chemical weapons . Dempsey's letter, dated July 19, listed U.S. assets in the region including Patriot missile defense batteries in Turkey and Jordan, as well as F-16 jet fighters positioned to defend Jordan from possible cross-border trouble. In addition, the Pentagon has sent four warships armed with cruise missiles to the region. According to U.S. officials, updated options offered the president in recent days included: . â€¢ Cruise missiles fired from one of four Navy destroyers deployed in the Mediterranean Sea. The missiles would be used to strike "command and control" facilities such as command bunkers, or the Syrian regime's means of delivering chemical weapons: artillery batteries and launchers. There is no indication that the missiles would strike at actual chemical weapons stockpiles. â€¢ Military jets firings weapons from outside Syrian airspace. This option carries additional risks and is considered less likely. "They have to be careful to do this in concert with our allies," Democratic Rep. Adam Schiff of California, a member of the House Intelligence Committee, told CNN on Sunday, adding that "I don't think the White House is going to want to risk American lives by sending pilots over Syria, so that really limits our options to cruise strikes and think that's probably where the White House is going to go." U.N. chemical weapons inspectors reach alleged attack site . Cruise missile strikes could be "very punishing" on al-Assad's missile supplies and aircraft without going after the chemical weapons stockpiles to risk dispersing them, Schiff said. To Aaron David Miller, a vice president at the Woodrow Wilson International Center, the situation is forcing Obama to shift from being an "avoider-in-chief" regarding military involvement in Syria. "It's almost inevitable that the president will authorize some form of military action," Miller told National Public Radio in an interview broadcast Monday. He said he expected a significant response that amounts to "a warning that lays down this time a red line that the president intends to enforce, not one that turns pink." "It cannot simply be a couple of cruise missiles into a storage shed somewhere," Miller said, adding that the goal was to deter al-Assad rather than topple him or radically shift the balance in Syria at this time. "The president's not on the verge of becoming the cavalry to rescue the country." Schiff agreed that Obama has little choice but to respond strongly. "In terms of the credibility of the White House," he said, "the cost of not acting now, I think, exceeds the cost of acting."
