The beginning of this color film has two short clips demonstrating high-speed photography. The first is of a piano wire being struck and the resulting vibrations, followed by a mousetrap being set off with a pencil. The rest of the film includes W. Bradford Luther, Jr. (who discoverd the Vineyard LIghtship with Edgerton) and footage of outfitting the Trieste with sonar instruments in preparation for expeditions in the early 1960s. It includes fieldwork being done in New England and tests of equipment in the Charles River [sonar]. There are multiple types of probes filmed and Harold Edgerton working with signaling equipment. Also filmed are many Navy ships, their crew and some other, unidentified men in uniforms. The original film is a 16 mm color Ansco and Kodachrome film.
