Okinawa Times and Ryukyu Shimpo reported that a U.S. Navy airplane used a Navy ramp at Kadena AB on Wednesday afternoon apparently in violation of a bilateral agreement prohibiting the use of the facility by planes with their engines running. The Okinawa Defense Bureau reportedly lodged a protest over the incident in which a P-8A maritime patrol aircraft taxied from the ramp to a taxiway with its engine on. Noting that a similar incident involving a different Navy airplane occurred at the Navy ramp in early June and that base authorities apologized a few days later, the papers wrote that local officials and residents are displeased and distrustful over the repeated failure by the U.S. military to comply with the U.S.-Japan pact on noise reduction that states the ramp can be used only as a “warehouse and/or a maintenance yard.”
