Robert Henn was the pilot for WHIO Airscout and WING Skywatch from 1980-1995. The collection consists mainly of aerial photographs (all 35mm slide format) of the Dayton metropolitan area, including especially Trotwood, Brookville, and downtown Dayton. Photos (non-aerial) of aircraft on display at the Dayton Air Show are also included. Most slides are identified at the item level by the creator, with a description and date written on the slide.
