Unmanned aerial vehicles are becoming divisive. Their battlefield roles range from the benign, like carrying supplies to U.S. troops on the ground, to the deadly, like the increasing drone attacks in Yemen and Pakistan. As UAVs are used more, embarrassing incidents also rise?ground controllers losing control of test drones or crashing them on missions. Here's a roundup of the good, bad, and ugly incidents.
By Jon M. Chang
\nTwo years after its maiden flight, we still don\'t know the X-37B\'s purpose. According to the Pentagon, the general objective of the space plane\'s second mission, USA-226, is to test new aerospace technologies, like improved guidance systems and thermal shielding, before they are implemented in other spacecraft. But wilder ideas about the craft have been floating around, such as space bomber or spyplane.\n
\nWe do know that the X-37B has been in orbit on its current mission for more than a year; it launched in March 2011. Based on X-37B\'s spectacular success, future missions for the spacecraft could include carrying more elaborate experiments into space and then safely returning them back to earth for further inspection and analysis. It\'s scheduled to land later this month.\n

Vijay Kumar from the GRASP Laboratory at the University of Pennsylvania is researching how to coordinate a team of drones to use for construction (and to play the James Bond theme song). Other projects include improved control and administration of pesticide use on crops and faster search-and-rescue operations in the remote areas. \n
\nMore than 15 universities have been certified to operate drones in U.S. airspace. More will certainly come after September 2015, the Federal Aviation Administration\'s deadline to set guidelines for opening U.S. airspace to more UAVs.\n

The Fire Scout drone wandered from the southern coast of Maryland toward Washington, D.C., eventually crossing into the district\'s restricted airspace. The Navy regained control of the drone 40 miles before it reached Washington, forcing it to land and avoiding further panic or embarassment. \n
\nCapt. Tim Dunigan, then the Navy\'s head of the Fire Scout project, blamed the problem on software; the helicopter should have made a return trip once it lost contact with the Navy. Losing control of a drone so close to restricted airspace gave the Navy a bit of a public relations black eye. The Fire Scout project was grounded in April of this year, perhaps due to two drone crashes in a week.\n

On Aug. 20, 2011, one of Northrop Grumman\'s Global Hawk drones crashed near the Pakistan?Afghanistan border. According to the crash report, maintenance workers didn\'t know enough about the differences between the various Global Hawk models. They did not apply thread-locking compound to better secure some of the screws that held the plane\'s electronics in place. As a result, the plane\'s vibrations jarred loose some components, damaging a critical electrical connection and disabling the plane\'s aileron and spoilers. \n
\nIn short, a $72 million drone crashed to the ground because of loose screws. However, Northrop Grumman addresses the mechanics mix up and continues to manufacture the Global Hawk.\n

Ghods Aviation in Iran manufactures the Ababil, but other countries and groups in the region and beyond have used it. Hezbollah tried to attack Israel with the Ababil in 2006, but all drones were shot down before they could cause damage. The Ababil may pale in comparison to modern U.S. drones, but it\'s still worth keeping an eye on. It\'s suspected that the Sudanese government used the drone to attack rebel forces earlier this year.\n

The U.S. claims that the drone was surveying Afghanistan, veered off course, and crashed in Iran due to technical problems. Iran is skeptical, saying that the drone was always intent on spying on Iran, and that it was able to be taken down due to electronic jamming by Iranian forces. Regardless of who\'s right, the drone was captured in Iranian airspace and the U.S. shouldn\'t expect them to return it. They\'re more than willing to send over a toy replica though.\n

But unlike the Ababil, these Streaker drones were actually made in the United States. \n
\nBack in the 1970s, Beechcraft, the plane\'s manufacturer, intended the Streaker to be the target in moving target practice for guided missiles. In the U.S., the plane is now obsolete. But according to an anonymous military official, North Korea is working to reverse-engineer Streaker to create a more capable attack plane. We shall see.\n

Security Council about Iraq, he cited the CIA\'s assertion that Saddam Hussein\'s regime had modified MiG-21 jets into chemical-weapon delivery systems. Other international intelligence agencies have also asserted that the regime had drones that could deliver chemical weapons. However, the Air Force disagreed, saying that the country\'s small drones were intended for reconnaissance.\n
\nYears after Hussein\'s capture, an in-depth government review of Saddam\'s weapons programs confirmed that the Air Force was right?the drones were incapable of performing any large-scale attack. The drone error was just one in a series of intelligence missteps in the run-up to the Iraq War.\n

THE GOODThe K-Max helicopter, certified to fly as far back as 1994, is a synchropter? a helicopter with intermeshing rotors that spin in different directions to optimize lift. It can operate without a tail rotor. Since its deployment in December of last year, K-max has delivered more than 1 million pounds of cargo and supplies to Marines stationed in Afghanistan, decreasing the need for trucks to travel routes that could be lined with roadside bombs. Beyond military purposes, the unmanned vehicle could also be used like its civilian relatives, assisting with construction projects and providing disaster relief.
