Historical Notes
  • The Legendary Norden Bombsight by Albert L. Pardini, published by Shiffer Military History,Atglen,PA.
  • John Osgood wrote:
    Might be of interest to you that the last use of the sight, as far as I know, was during Vietnam. Observation Squadron 67 (VO-67) used it to drop sensors on the Ho Chi Min trail.
    The squadron used P2V-5 aircraft.

Other information
  • Scott Baker (2004) says there is "one (in a glass case) at the Air Force Museum at Dayton, Ohio."
  • (August 2005 - Q R Stottlem says "Back in 1993 I learned that the U S. Air Force Museum, 1100 Spaatz Street, Wright Patterson AFB, OH 45433-7102 had and would copy originally restricted material on the M9 Norden bombsight, a 370 page manual for $37 and Lowry Field manual for $25. I purchased both and also received a copy of the original excellent Popular Science article of June 1945. The museum may still offer this service. I'll be glad to furnish a limited number of copies of the P. S. article to whoever desires copy."
