X-WR-CALDESC:15 April 1969: Navy EC-121 shot down by North Korean MiGs over
  the Sea of Japan. The aircraft\, Bureau number 135749\, c/n 4316\,[3] bor
 e the tail code 'PR-21' and used the radio call sign Deep Sea 129. Thirty-
 one U.S. Navy and Marine Corps personnel were killed. On 15 April 2013\, N
 IOC Misawa commemorated the 44th anniversary of this loss with a special c
 eremony. See the the link below to an NSA document regarding the NSA & the
  EC-121 shootdown.\n\nDeep Sea 129's assigned task was a routine Beggar Sh
 adow signal intelligence (SIGINT) collection mission. Its flight profile n
 orthwest over the Sea of Japan took it to an area offshore of Musu Point\,
  where the EC-121M would turn northeast toward the Soviet Union and orbit 
 along a 120-nautical-mile (222 km) long elliptical track. These missions\,
  while nominally under the command of Seventh Fleet and CINCPAC\, were act
 ually controlled operationally by the Naval Security Group detachment at N
 SF Kamiseya\, Japan\, under the direction of the National Security Agency.
 \n\nAt 12:34 local time\, roughly six hours into the mission\, the Army Se
 curity Agency and radars in Korea detected the takeoff of two North Korean
  Air Force MiG-17s and tracked them\, assuming that they were responding i
 n some fashion to the mission of Deep Sea 129. In the meantime the EC-121 
 filed a scheduled activity report by radio on time at 13:00 and did not in
 dicate anything out of the ordinary. 22 minutes later the radars lost the 
 picture of the MiGs and did not reacquire it until 13:37\, closing with De
 ep Sea 129 for a probable intercept. \n
