TOKYO — Japanese officials moved to control diplomatic damage after an air traffic controller was questioned here for posting secret American flight information on his blog, including the detailed flight plans of Air Force One last November. 
 
 The Transportation Ministry said Saturday that the controller, who works at Haneda Airport in Tokyo, could face charges of leaking national secrets. Japanese officials appeared embarrassed by the breach, which also included the flight data of an American military reconnaissance drone. 
 
 Tokyo is apparently worried that the episode could raise new doubts in Washington about Japan’s ability to handle delicate information, after a scandal four years ago over the leak of American naval radar secrets. The newspaper Yomiuri Shimbun reported that Prime Minister Yoshihiko Noda may personally apologize to President Obama for the breach during a meeting this month in New York. 
 
 The ministry said the controller, who was identified only as a man in his 50s, posted the flight plan of Air Force One during Mr. Obama’s visit to Asia in November. It said the blog contained two pages of detailed information about the flight, including numerical data and a map showing the plane’s route. 
 
 Air Force One’s flight details are usually kept secret to protect the president. The ministry said the blog contained no explanation of the numbers or images, which would have been largely incomprehensible to a layman. 
 
 It said the controller was being questioned after a caller tipped off officials last Monday. The ministry also said that the controller did not appear to have acted with ill intent and told the authorities he posted the information to show his friends. 
 
 The controller posted 12 pages of delicate information that included flight plans of a Global Hawk drone that was gathering radiation readings near the crippled Fukushima Daiichi nuclear plant, the ministry said. 
 
 For Japan, the episode is uncomfortably similar to a leak in 2007 of classified information about the United States Navy’s advanced Aegis combat radar system, which is also on Japanese warships. A Japanese Navy officer was arrested for copying data about the radar onto CD-ROM disks and distributing them to classmates at a naval school. 

 An air traffic controller at Tokyo's Haneda Airport faces possible punishment after posting confidential information on his blog, including the flight plan for President Barack Obama's visit to Japan last year, news reports said Saturday. 
 
 The controller, identified only as a man in his 50s, uploaded a dozen photos he took of flight plans and radar screens onto his personal blog, according to public broadcaster NHK. A post about Air Force One included its route as well as takeoff and landing details which are normally kept secret for security reasons. 
 
 Obama traveled to Japan in November to attend the Asia-Pacific Economic Cooperation forum in Yokohama. 
 
 The controller also posted the flight plan for an unmanned American reconnaissance aircraft that was dispatched to gather radiation data from the crippled Fukushima Dai-ichi nuclear power plant, Kyodo News agency said. All the images have since been deleted. 
 
 The transport ministry is investigating and considering disciplinary action, Kyodo and NHK said. Calls to the ministry were not answered Saturday. 
 
 Kyodo said Prime Minister Yoshihiko Noda, who took office eight days ago, will explain the findings of the investigation to Obama when he travels to Washington later this month. 
 
 Noda has said he wants to strengthen ties between the countries and has expressed strong support for the U.S.-Japan security alliance.
– An air traffic controller in Tokyo is in hot water after posting secret information on his blog, including the flight plan of Air Force One when President Obama visited last year. The controller apparently wasn't looking to cause trouble but to impress his friends with all the cool stuff he was privy to in his job at Haneda Airport. He also posted details on the flight plan of a US drone gathering data near the Fukushima Dai-ichi nuclear plant, according to Japanese media reports rounded up by AP. Japanese officials are so embarrassed that Prime Minister Yoshihiko Noda might apologize himself to President Obama for the breach when he visits the US next month, notes the New York Times. The controller is identified only as a man in his 50s. He was being questioned after an anonymous tipster informed authorities about his blog.
