The Jets modified their helmet and logo design for 1964, switching from a single green stripe to two parallel green stripes down the center of the helmet crown. The jet-airplane logo decal was replaced by a white football shape outlined in green, with the word "JETS" in thick green sans-serif capitals over "NY" in green outline serif lettering, and a miniature football at bottom center.
Both the Jets and the baseball New York Mets moved to Shea in 1964. The team's original owner when it was the Titans, Harry Wismer, hoped the team could play in Shea beginning in 1961, but funding difficulties and legal problems delayed construction of the stadium. Wismer signed a memorandum of understanding in late 1961 to secure the Titans' new home. That memorandum recognized that the Mets would have exclusive use of the stadium until they had completed their season. As the Jets moved to Shea under new ownership, they were, in most years, required to open the season with several road games, a problem which would become worse in 1969 and 1973 when the Mets had long playoff runs.
