His large format (mostly 5x7) images of American engineering, architecture and landscapes comprise a large percentage of the photographic collections of the Historic American Engineering Record, Historic American Buildings Survey, and Historic American Landscapes surveys housed in the Prints and Photographs division of the Library of Congress. Retiring after 35 years with the National Park Service in 2013, Jet in recent years has been exploring the built environments and landscapes of France, Italy, and India. He is interested in recording structures of world heritage significance as well as accepting commissions from architects, engineers, and preservationists working in the private sector as well as government.
