While speaking of the F111, My Uncle who lived 2 miles from my grandpa's farm worked ad General Dynamics during the development of the F111 project as a class B electrician, and it was his fault you might say that the plane ever flew. He discovered what could be a potentially serious chaffing problem in how electrical sensor harness of the wing deployment was to be routed. brought it to the attention of the developing engineers, who made a few changes in the design during the prototyping stage. He received a citation and a plaque thanking him for his input.
