[Q]: Call them drones; call them toy airplanes with digital cameras dropped into their girths. Either way, South Korean defense officials said on Friday they were sure that they came from North Korea and that they were up to no good. Three diminutive single-engine unmanned propeller planes that look like they could have come from a hobby shop were found on the ground in March and April in parts of the South near the border with the northern Communist regime. Though the low-tech buzzers don't seem to represent a major danger, they come in the shadow of North Korean missile launches and the impending countdown to the test of a nuclear device. And they made it through South Korean air defenses. Ministry of National Defense officials in Seoul immediately suspected that the sky-blue colored fliers belonged to Pyongyang. They formed an investigation team with the United States in mid-April to analyze the "travel log file" and photos taken by the drones and announced the results on Friday. Scientists found a "smoking gun that all three were sent from North Korea and are programmed to return to North Korea," South Korean defense spokesman Kim Min-soek said. Photos the drones took along on their journey corroborate their flight path, he said. Precarious cargo . Had the mechanical carrier pigeons made it back home, they would have delivered precarious cargo, but it would have been far from precious. Japanese-made digital cameras, which look like they could be of the consumer variety, were inserted into the bellies of the drones and had taken aerial photos of the South from around the border region. All three were programmed to fly over military facilities, and two of them had images of targets of military interest -- strategically important islands near the demilitarized zone, and the Blue House, residence and office of South Korea's President Park Geun-hye. Images from the third drone were not available to South Korean investigators. A wild ginseng digger had stumbled upon the plane and had deleted its memory card so he could use it himself, the Korea Times reported. The planes were not capable of transmitting images back to North Korea in real time, and the photos themselves were no better than what one might see on a service akin to Google Earth, Kim said in a previous briefing. Limited capabilities . There is little danger the drones could have made it far into South Korea. The type of drone is not used for long-range missions, a defense analyst said. Instead they're better suited to see what the enemy is up to on the other side of a hill or wall. "It has quite a small range, it doesn't have very long endurance so it would only be up there for a few hours. You would use those to see what the other guys are doing in a battlefield environment," said James Hardy, the Asia Pacific editor of IHS Jane's Defence Weekly magazine. "They're very much closely built off a remote-controlled aircraft that you can buy in a toy store. They're just a militarized version of that," Hardy said. The Korean drones are nowhere near as sophisticated as those used by the United States in Pakistan, Yemen and Afghanistan, he said. They would also not make much of a weapon, if someone decided to stuff explosives into them, Kim has said. "Even if they are to be used for future attacks, (they) can only carry 2-3 kilograms of TNT and cannot cause huge damage." North Korea has flaunted similar, larger UAVs at military parades in recent years, and some of them have been spiked with explosives, Hardy said. Video footage shows North Korean exercises using them as missiles, but it's an expensive way to build a bomb, he said. And it could only take out a single vehicle or ship. 'Tis the season . Spring is traditionally a time of high tensions between Pyongyang on the one side and Seoul and Washington on the other. Annual U.S.-South Korean joint military drills, that ended on April 7, drew criticism from North Korea, which views the exercises as "dress rehearsals for invasion," according to analyst James Person from the Woodrow Wilson Center. In March, Pyongyang fired two mid-range ballistics missiles off its eastern coast, in an apparent response to the drills. Days later, the two sides fired hundreds of shells across the Northern Limit Line, their disputed maritime border. The shells were shot into the sea, not at hard targets. North Korea also warned it was preparing to test another nuclear device. "It's all good stuff because it allows the North Koreans to do something provocative and slightly annoying which might embarrass South Koreans, but it's not provocative enough to create a proper military response," Hardy said. Slipping through . The drones would fit well into that category, since they slipped through South Korean air defenses. They are made of polycarbonate, which is difficult to detect with radar, according to South Korea's Yonhap news agency. They fly at an average speed of about 110 km per hour (68 mph) at an altitude of 1.3 km (.8 miles). They were launched in North Korea from three locations, South Korea's defense ministry said: Near the Kaesong area, 27 kilometers southeast of Haeju and 17 kilometers from Pyonggak. South Korea's defense ministry called the intrusion by the drones a violation of the truce that ended the bloody conflict between North and South Korea in 1953. Kim said Seoul will send a warning via the United Nations to Pyongyang and tighten air defenses as a response to the drones.

[Q]: (CNN) -- Investigators probably will have to use dental records to identify some of the eight people who were killed in a wreck involving a church bus and two other vehicles in eastern Tennessee, a Tennessee Highway Patrol official said Thursday. Some of the bodies in Wednesday's crash were burned or otherwise made unrecognizable, hindering authorities' ability to notify all of the victims' families about the deaths, highway patrol Sgt. Bill Miller said. "The crash is so horrific ... it's probably the worst that I have seen in my career ... and I've worked in several, several counties in my" 17 years on the job, Miller said. More from CNN affiliate WBIR . The bus, owned by a North Carolina church, was carrying a group of seniors on their way back home from a religious conference when one of its tires malfunctioned, sending the bus across a median on Interstate 40 and crashing into an SUV and a tractor-trailer, authorities said. Church bus was carrying seniors home from a jubilee . Eight people were killed: Six on the eastbound bus; one of three occupants of the SUV, and the tractor-trailer driver, the Tennessee Highway Patrol said. Two of the 14 other people who were hospitalized after the wreck had been released by Thursday morning, said Travis Brickey, a representative of the University of Tennessee Medical Center. Two people were in critical condition; seven were in serious condition, and three were in stable condition, Brickey said. None of the victims' names was released. The church group -- about 18 people including the driver, Miller said -- was returning to the Front Street Baptist Church in Statesville, North Carolina, after attending the 17th annual Fall Jubilee conference in Gatlinburg. Indiana bus crash kills pastor, pregnant wife, chaperone on teen trip . The group of senior citizens was called "Young at Heart," said Rick Cruz, the church's pastor. Twelve of the hospitalized victims -- including the two in critical condition -- are church members, Cruz said Thursday morning. "It's been a very long night for all of us here," Cruz told reporters. "We are thankful for all the prayers and support that we've been receiving." More from CNN affiliate WHNS . The wreck happened about 2 p.m. Wednesday in Jefferson County, about 40 miles east of Knoxville, the Tennessee Department of Safety said. Miller said it wasn't clear exactly what happened to the bus tire, other than it malfunctioned or failed in some way. The bus swerved across a grassy median and struck the SUV before hitting the tractor-trailer, he said. The bus came to rest on its side, pinning some of its occupants, he said. More from CNN affiliate WATE . Video from the site showed smoke rising from the tractor-trailer. Some people walked out of the bus on their own, but emergency personnel had to extricate others, Miller said. "This was such a horrific crash that determining if seat belts were used or not ... may be extremely difficult to impossible to determine," he said. Miller said it's too early to know whether charges will be filed in connection with the wreck. More from CNN affiliate WVLT . Girls injured when school bus overturns in Kansas .

[Q]: Kansas City, Missouri (CNN) -- The General Services Administration, already under investigation for lavish spending, allowed an employee to telecommute from Hawaii even though he is based at the GSA's Kansas City, Missouri, office, a CNN investigation has found. It cost more than $24,000 for the business development specialist to travel to and from the mainland United States over the past year. He is among several hundred GSA "virtual" workers who also travel to various conferences and their home offices, costing the agency millions of dollars over the past three years. Under the program, employees work from home and may live in another state from the region in which they're actually assigned. The Kansas City employee, who started his job in January 2011, is paid $84,440 and works from his home in Honolulu, a GSA representative confirmed. In the past year, according to GSA travel records, the employee has flown back to the mainland nine times for conferences and meetings. Four of those trips were to St. Louis; four were to Washington, with a side trip to Cincinnati; and one was to San Diego. The total cost to taxpayers was $24,221. Jason Klumb, the GSA's regional administrator for Kansas City, defended the hire. "The cost of that travel was included in the consideration of his candidacy as an employee as compared with the other applicants," Klumb said. "And when factoring all of those in, it was determined that he was the best candidate, even in light of the cost that would be incurred." Klumb called the GSA's teleworking program "a successful program that's going to lead to cost savings for taxpayers." But a GSA spokeswoman said, "We are not going to defend this type of travel." And a GSA employee in Kansas City, who requested anonymity, said that hiring someone in Hawaii to work for the Kansas City region was ludicrous. "It doesn't make sense," the employee said. "When you consider everything you need when you hire someone, it would have been better to look for someone in the Kansas City area. It would have reduced the cost of travel by at least 70 percent when you look at just the airfare of what it takes to from Honolulu to Washington, D.C., where a lot of business is done." Dan Tangherlini, who was appointed acting GSA administrator this year, said the agency was examining the cost of the entire teleworking program. "I think the most important part for the GSA to think about is make sure we open ourselves up, avail ourselves to all the smart people in the country, but then also make sure we have a clear business case," he said. "If we have someone who is working in Nebraska but reporting to Boston, there has to be a clear explanation for what value they're providing, and you've got to give me the business case. You've got to explain to me why that's a cost-effective move for the American people, and that's a new standard that we're asking everyone at GSA to adhere to." The GSA "virtual employee" program is different from telework programs offered by many private companies including CNN's parent company, Turner Broadcasting, in which some employees are encouraged to work from home some days of the week, partially to reduce traffic congestion. The House Committee on Oversight and Government Reform requested details about the GSA's teleworking program in June. That followed disclosures that 95 virtual employees, including 12 in supervisory positions, spent nearly $750,000 in travel costs between October 2010 and June 2011. "The American people have a right to know that federal bureaucrats who enjoy the benefits of virtual work are eligible and responsible stewards of the taxpayer dollars that support the program," according to a letter from committee Chairman Rep. Darrell Issa, R-California, to the GSA. The details requested by Issa about the GSA program have not been provided to the committee. CNN also requested the information more than two months ago through the federal Freedom of Information Act but has been repeatedly told by the GSA that FOIA staff members have not finished compiling the material. The General Services Administration, which has more than 12,600 employees and a $26.3 billion budget, is a relatively obscure federal agency that handles government real estate and other non-military procurement. Congress launched an investigation into the GSA after a scathing inspector general's report issued this year showed lavish spending -- $823,000 -- at the agency's Western Regions Conference in Las Vegas in October 2010. The controversy became politically toxic after reports and video clips of the lavish conference were released. The revelation prompted taxpayer indignation, embarrassed the administration and put a spotlight on wasteful spending by the GSA. Jeff Neely, the GSA official who organized the conference, resigned, as did the agency's administrator, Martha Johnson. Two of Johnson's deputies were fired, and eight other employees left the agency. Tangherlini, a former Treasury Department official, took over as acting GSA administrator. In addition to the Las Vegas conference, the GSA apparently spent $330,000 to relocate an employee from Denver to Hawaii and probably millions more on other employees over a two-year period, according to a transcript of an interview with a GSA event planner. And 84 GSA employees, most of them supervisors or other senior staff -- all subjects of inspector general investigations -- are still collecting their bonuses, totaling more than $1 million in taxpayer money. In July, a CNN investigation revealed that the GSA's Kansas City office spent more than $20,000 to send employees to cooking classes to build team spirit. While the classes do not amount to a significant sum of money in the world of trillion-dollar government budgets, insiders said it was part of the free-spending culture that went on for years at the GSA's Kansas City regional headquarters. GSA spokeswoman Betsaida Alcantara said in a statement this year that all the agency's practices are under a top-down review. CNN's Sara Anwar, Elizabeth M. Nunez and Tom Cohen contributed to this report. Watch Erin Burnett weekdays 7pm ET. For the latest from Erin Burnett click here.
