Norden bombsight
It was originally assigned Victor (unit-assigned identification) number 9, but on 1 August it was given the circle R tail markings of the 6th Bombardment Group as a security measure, and it had its Victor number changed to 89 to avoid misidentification with actual 6th Bombardment Group aircraft. Its nose art was painted after the Nagasaki mission. The name purportedly referred to the talents of the bombardier, Captain Kermit Beahan, with both the Norden bombsight and with women.
