 The federal government proposed keeping Palm Beach Air Force Base as a permanent military facility, but ultimately decided to return it to Palm Beach County control in 1959, and the name was reverted to Palm Beach International Airport.The 1950s saw another boom in population, partly due to the return of many soldiers and airmen who had served or trained in the area during World War II.Also, the advent of air conditioning encouraged growth, as year-round living in a tropical climate became more acceptable to northerners.
