Example Input: Hurlburt Field, Florida (CNN) -- An Air Force CV-22 Osprey crashed Wednesday during a routine training mission north of Navarre, Florida, injuring five crew members aboard, a military official said. The crash occurred about 6:45 p.m. at Hurlburt Field's Eglin Range, said Amy Nicholson, chief of public affairs at the airfield. The five injured crew members were taken to an area hospital, Nicholson said. The extent of their injuries was not immediately known. The cause of the accident is under investigation, she said. The Osprey was assigned to the 1st Special Operations Wing, the Air Force said. The tilt-rotor aircraft can fly like an airplane and land like a helicopter. The Army began developing the Osprey in 1982, though the program was nearly scrapped in 1989 when then-Secretary of Defense Dick Cheney sought to cancel it because of ballooning costs. Questions were raised about the safety of the Osprey after two crashes, including one in 1992 at a Marine Corps air base in Virginia that killed the crew. In late 2000, the Marine Corps grounded the Osprey fleet after two crashes -- one in Arizona that killed four crew members and 15 passengers, and another in North Carolina that killed the crew. A redesign was ordered on the Osprey, and it resumed flights in 2002. The Air Force began using Ospreys in 2008 after testing the aircraft in 2006. They were first deployed by the Marines in Iraq in 2007 after 18 years and $20 billion in development. <sep>Did the Marines or the Air Force use the Osprey first?<sep>Air Force

Example Input: The CIA's senior management saw problems with the armed Predator as well, problems that Clarke and even Black and Allen were inclined to minimize. One (which also applied to reconnaissance flights) was money. A Predator cost about $3 million. If the CIA flew Predators for its own reconnaissance or covert action purposes, it might be able to borrow them from the Air Force, but it was not clear that the Air Force would bear the cost if a vehicle went down. Deputy Secretary of Defense Wolfowitz took the position that the CIA should have to pay for it; the CIA disagreed. Second, Tenet in particular questioned whether he, as Director of Central Intelligence, should operate an armed Predator." This was new ground,"he told us. Tenet ticked off key questions: What is the chain of command? Who takes the shot? Are America's leaders comfortable with the CIA doing this, going outside of normal military command and control? Charlie Allen told us that when these questions were discussed at the CIA, he and the Agency's executive director, A. B." Buzzy" Krongard, had said that either one of them would be happy to pull the trigger, but Tenet was appalled, telling them that they had no authority to do it, nor did he. Third, the Hellfire warhead carried by the Predator needed work. It had been built to hit tanks, not people. It needed to be designed to explode in a different way, and even then had to be targeted with extreme precision. In the configuration planned by the Air Force through mid-2001, the Predator's missile would not be able to hit a moving vehicle. White House officials had seen the Predator video of the "man in white." On July 11, Hadley tried to hurry along preparation of the armed system. He directed McLaughlin, Wolfowitz, and Joint Chiefs Vice Chairman Richard Myers to deploy Predators capable of being armed no later than September 1. <sep>Why did the Hellfire warhead carried by the Predator need work?<sep>It didn't have the ability to hit moving targets. It was created to hit tanks, not people
Example Output:
Yes
