Captain Percival and his plane with joy flight passengers

Edgar Wikner Percival (23 February 1897 – 21 January 1984) was a noted Australian aircraft designer and pilot whose aircraft were distinguished by speed and grace. Percival went on to set up the Percival Aircraft Company, a British aircraft company in his own name. (Wikipedia)

During the period from WW1 to the mid 1930s, aircraft made heavy use of both Greenmount and Kirra beaches, and the area now taken up by the Greenbank development, as landing places.

Perhaps the two better known aviators in the early days were Captain Edgar Percival, who always favoured Greenmount, and Captain P. W. Snell, who operated from Kirra beach. Capt. Percival was an aircraft engineer and had a shop at Richmond, NSW, which he used to set up imported aircraft. Each year he headed north, and did a brisk trade taking some of the thousands of holiday makers in the Twin Towns on joy flights over the town.
