Hollingshead Airport is a privately owned restricted-use airport located in Clarksboro, New Jersey in the United States. It was previously known as Peaslees Airfield. It is located on the former estate of Ambassador Amos J. Peaslee. Hollingshead Airport is located 4.7 nautical miles from Philadelphia International Airport. The airport is situated inside the Class B airspace for Philadelphia International Airport. It is the only Restricted Use airport in the United States within Class B Airspace. The airport and the first hangar were designed by Vincent Kling, a well known Philadelphia architect and avid private pilot who oversaw many of the renovations and additions on the Peaslee estate. Kling would later go on to author the Master Plan for Ronald Reagan Washington National Airport. During construction of the airport tower, Amos J. Peaslee had the workmen install a stone from the Great Wall of China, which he had obtained during a visit to the wall.
