Mr. George Whitaker, Sr., a senior manager at the Ford Motor Companys Rouge Plant in Detroit, Michigan, told attorney (and professor of criminal justice) Doug Weldon in August of 1993, in a tape recorded conversation, that after reporting to work on Monday, 25 November 1963, he discovered the JFK limousine  a unique, one-of-a-kind item that he unequivocally identified  in the Rouge Plants B building, with the interior stripped out and in the process of being replaced, and with the windshield removed. He was then contacted by one of the Vice Presidents of the division for which he worked, and directed to report to the glass plant lab, immediately. After knocking on the locked door (which he found most unusual), he was let in by two of his subordinates and discovered that they were in possession of the windshield that had been removed from the JFK limousine.
They had been told to use it as a template, and to make a new windshield identical to it in shape  and to then get the new windshield back to the B building for installation in the Presidential limousine that was quickly being rebuilt. Whitaker told Weldon (quoting from the audiotape of the 1993 interview): And the windshield had a bullet hole in it, coming from the outside through
it was a good, clean bullet hole, right straight through, from the front. And you can tell, when the bullet hits the windshield, like when you hit a rock or something, what happens? The back chips out and the front may just have a pinhole in it
this had a clean round hole in the front and fragmentation coming out the back. Whitaker told Weldon that he eventually became superintendent of his division and was placed in charge of five plant divisions. He also told Weldon that the original windshield, with the bullet hole in it, had been broken up and scrapped  as ordered  after the new windshield had been made.
