On the day cease-fire agreements ending the war in Vietnam are signed in Paris, crews flying Boeing B-52 Stratofortresses bomb logistics targets such as truck parks and storage areas south of the 20th Parallel. At 4:10 p.m. local time, the last USAF aircraft to fly over Hanoi, a Ryan AQM-34L drone, photographs results of the Operation Linebacker II raids for bomb damage assessment. The cease-fire takes effect at 7 p.m. EDT, which makes the cease-fire date effective Jan. 28 in Vietnam.
When the Air Force sets a new program baseline for the B-52 re-engining this fall, there will be “some” cost increase, because the project wasn't previously fully funded, and the Air Force has a better handle on actual supplier costs and knowledge from ground testing, program officials said.
