A top Chinese official last year warned that FONOPS could "end in disaster".<br /><br />Friday's exercise was far from the disputed areas of the waterway, rich fishing grounds which contain largely unexplored oil and gas deposits. Kilby there were "contacts" with merchant, fishing and military vessels in the past two weeks, though no "incidents". He did not elaborate. China has been guarded in its response to the latest U.S. mission, which started one day after Beijing finished its own aircraft carrier exercises.<br /><br />It said it respected freedom of navigation and hoped the United States could "contribute positive energy towards this good situation". The crew aboard Carl Vinson will spend five months in Asia. During Friday's drills, one fighter missed its landing, or "recovery", and was made to repeat the exercise, circling the vast ship before making a perfect landing.<br /><br />Captain Douglas Verissimo, the skipper of Vinson, said the exercises included rigorous checks. Aircraft were simulating combat and bombing runs, performing over and over until flaws were ironed out.</div>
