East Whiteland Township, Ricoh USA Inc., and the Tredyffrin Easttown Historical Society, with the invaluable help of many individual financial supporters, will hold a dedication ceremony for a new historical marker honoring the legacy of the Main Line Airport, which stood for over 50 years on what is today occupied by the Great Valley Corporate Center, in Malvern, Pa.

This dedication will be held within the Great Valley Corporate Center on the campus of Ricoh at 70 Valley Stream Parkway, near the intersection of Valley Stream Parkway and Swedesford Road, on Thursday, October 5, 2017 at 2:00 pm. All are welcome.

Few people today are aware of the existence of the legendary Main Line Airport, let alone its many contributions to fixed-wing and rotary-wing aviation. It was one of Pennsylvania's earliest country airfields, and served aviation from the 1920s through the 1970s. On this property during the 1930s, major research advancements in rotary-wing stability and control were developed and later incorporated into the world's first successful helicopter. This field, also called by many the “Paoli Airport,” served for decades as a flight training center for hundreds of fixed-wing pilots in both war and peace. In the uncertain early months of World War II, a Civil Air Patrol squadron established at the Main Line Airport provided desperately needed manpower and material to support America's battle against marauding German submarines along America's mid-Atlantic coast. And further rotary-wing innovations created here in the 1950s-60s contributed to the helicopter as we know it today. The importance of the Main Line Airport cannot be overstated.

At the conclusion of this brief ceremony, there will be, weather permitting, an exciting flyover of some of the historic aircraft that would have flown into the Main Line Airport. A reception with light refreshments will follow at the adjacent headquarters of Ricoh. At this reception, we also look forward to welcoming several individuals who actually flew out of the Main Line Airport and its subsequent heliport so many years ago, and will have on display many photographs depicting this historic site.
