摘要

At a ceremony on Friday, June 17, 2016, AHS International dedicated its fifth Vertical Flight Heritage Site in Springfield, Pennsylvania. Beginning in March 1947, this site (which was then known as Morton, Pennsylvania) was the headquarters for Piasecki Helicopter Corporation, then the Vertol Aircraft Corporation in March 1956, and the Boeing Airplane Co. Vertol Division in April 1960, before Boeing consolidated its work in nearby Ridley Park in 1971.
