The pillars, now south of the new Veterans Hospital, were once one of the field boundary light arrangement to enable safe night flying from the early days of Corry Field. They were used between 1927 and 1934 to light the southern edge of the landing field that was only a grass area at the time (i.e. no runways). The lights had electrical and a gas system for added light augmentation as needed. The pillars are 15 to 20 feet tall and each held a 7 foot tall light as shown in an attachment. Two additional sets of shorter pillars were located along the western and northern field boundaries. These lights permitted safe clearance of trees and lit the landing areas for the early biplanes (without any on-board lights). Additional lighting and runway construction was started after 1934 as aircraft and airfield development proceeded.
