Times changed for the Thunderbird by 1997 when the final tenth-generation car rolled off the production line in Ohio. This wasn't Knudsen's only change to the Ford lineup though, he made the first-generation Mustang three inches wider before his successor Iaccoca would introduce the infamous second-generation model. This addition to the car came in 1970 and essentially acted as a part of the fifth thunderbird's facelift and attempted to give the Thunderbird the beak of an Eagle, incredibly patriotic. Legendary designer Larry Shinoda, of Corvette fame and thus a fan of pointed noses in his work, penned the beak.

Others refer to this as simply a “long nose”, like the one found on the 1969 Pontiac Grand Prix. At this time, the manager introduced a design quirk to the Ford Thunderbird called the Bunkie Beak by enthusiasts. But along his journey through the company he gave John DeLorean his break and led Pontiac to success in NASCAR A traitor to General Motors, 'Bunkie' became the President of Ford for a very brief stint. Joining the company before the United States had entered the Second World War, he worked his way up the ranks of Pontiac before departing in 1968. Semon “Bunkie” Knudsen had a long and successful history as a General Motors executive.
