FILE - In this April 5, 2014 file photo, pilots look out of a window from the cockpit in a U.S. Navy P-8 Poseidon plane as it taxies to the end of the runway to take off from Perth Airport on route to conduct search operations for missing Malaysia Airlines Flight MH370 in southern Indian Ocean, near the coast of Western Australia. Every day from the Perth airport and a nearby military base, about a dozen planes from several countries take flight to search for debris from missing Flight 370 _ so far without success. The U.S. Defense Department alone committed $7.3 million to the effort in the first month of the search, much of it spent on two U.S. Navy P-8 Poseidon planes that cost $4,000 per hour to fly.
