Very historical and proud Minot AFB, ND, 5th FIS F-106A Delta Dart 56-0461 was restored and repainted to represent 57-0231 "Red Bull One" for 87th FIS at KISAFB, MI. Thank you maintainers at Minot for taking such good care of her. She has her original tail number stenciled under the trailing edge of both elevons. This is required by the USAF Museum. Quick question: Does anyone from the 5th FIS know the story of "Backman's Bumps" on the bottom of each wing? Share it with us if you know.
