Why Lyndon Johnson's Air Force One Crew Installed A Fake Temperature Control

Lyndon B. Johnson's extensive use of Air Force One resulted in several additions being installed on the plane. Besides the fake thermostat from when he was vice president, other modifications were made to SAM 26000 while Johnson was president. This included the installation of doggy doors, which allowed his two beagles, Him and Her, to come and go from the conference room whenever they pleased. Johnson was obsessed with his dogs, and he would frequently bring them along with him during his travels (via Military.com). 

Johnson also had his office on Air Force One modified to his liking. It featured a giant leather chair surrounded by couches for people to gather around to work. His aides dubbed his large chair "the throne." While these additions were far from the craziest features on Air Force One, they were unique to Johnson's presidency.
