Built in the early fifties, a Grumman Navy Cougar jet airplane saw action on reconnaissance photo missions during the Korean conflict. It survived only to be relegated to a graveyard for planes in Litchfield, Arizona. However, its abandonment lasted only until 1959, when it was adopted by the Parks and Recreation Department of Anaheim, California. The aircraft was brought to Southern California and converted to a piece of play equipment in Anaheim's Boysen Park. In time, the pitter patter of little feet wore through the aluminum skin of the plane. The Anaheim park authorities, appreciative of the plane's popularity among the children, decided to take steps to preserve it as playground equipment. The Kaiser Cement and Gypsum Corporation was approached for information on using concrete for coating the aircraft. Contractor Bill Hentzes was called in to do the job. The backup work, or lathing, was basic to the project. One inch number 20 wire was stretched on all surfaces and attached with ringed furring nails. Because of the hardness of the plane's skin, pilot holes had to be punched prior to driving the furring nails home. A latex bond coat was sprayed slightly ahead of the scratch coat. The mix for the scratch coat was 1 part gun plastic cement to 2.5 parts washed plaster sand. The brown coat was of the same proportion, and both the scratch and brown coats contained 1 quart of latex per batch. The total thickness was 1 inch. The scratch coat was allowed to dry seven days before the application of the brown coat was made. Since every surface was expected to receive climbers, the surface was left rough to help eliminate the possibility of children slipping and falling off. It was soon discovered, however, that the rough surface provided a medium for children to express their frustrations in four letter expletives. Removal of the comments was almost impossible, due to the roughness and porosity of the concrete. A chemical company in Fullerton, was called upon to offer a solution. It came up with a two component polyurethane coating, colored light blue, which was applied to the surface of the concrete covered plane.
