Villamor Air Base, named for Filipino WWII pilot Jesús A. Villamor is the home of the Philippine Air Force (PAF) and shares runways with the Ninoy Aquino International Airport (NAIA). It is also known as Nichols Field or Nichols Air Base. Chiefly used as a PAF transport/helicopter airbase, it is also the military installation that the Philippine president uses when departing for foreign or domestic trips, though foreign departures are mostly done at the NAIA.
