The Seiler Family Aviation Collections holds textual, visual, and audiovisual materials from the military and commercial aviation careers of members of the Seiler family. Materials are dated from the 1950s through the 2010s, although the bulk of material fall within the 1980s-1990s. It has been arranged alphabetically by family member with each family member's materials in chronological order.

The first series, Gretchen (Seiler) Haskins, is primarily textual materials that provide a brief glimpse into Haskins' early military training and service, 1982-1987. It includes a press release about her nomination into the United States Air Force (USAF) Academy, pilot indoctrination completion certificate, special orders promoting her and other military personnel to 2nd Lieutenant, and a permanent change of station form assigning Haskins to Norton Air Force Base in California as part of "Ballistic Missile OF (AFSC)." There is also an undated color 3x4-inch snapshot of Seiler in her Academy jacket standing in front of wall of figure skates. A very small amount of additional materials relate to her professional career, including 2012 correspondence regarding joining the British Guild of Air Pilots and Air Navigators and an undated nametag from an Aviation Week conference that reads "Laureates / Gretchen Haskins / Helioffshore / Honoree."

The second series, Mary Seiler, has the largest amount of materials in the collection and pertains to Seiler's military and commercial aviation career, 1982-1995. Seiler's military career is reflected with her pilot graduation program, two clippings that mention Seiler, and two maps, including one of Turkey and a air refueling map around Loring Air Force Base in Maine. There are also two 1991 mission lists, one for Operation Desert Shield/Operation Desert Storm and one for Operation Provide Comfort.

A highlight in this series are the 10 color 8x10-inch digital prints. Images depict military aircraft, in flight on missions and during aerial refueling and on the ground; military personnel, and military buildings. Four prints are noted as being taken Desert Shield and Desert Storm. Identified locations include Jeddah, Saudi Arabia, Naval Support Facility Diego Garcia, and Vance Air Force Base, in Oklahoma. Identified persons include Staff Sergeant Tim Arsenault and Mary Seiler. The bulk of the prints include brief captions that provide context, including date, location, or names. Most of the prints are formatted as contact sheets, with four images to a sheet. Seiler's commercial aviation career is reflected in the assorted cockpit diagrams issued by American Airlines for the Boeing Model 757 and 767.

The final series, Richard Frank Seiler, is comprised of 40 black-and-white photographic negatives and five 16mm film reels all related to his military service in the 1950s in North Africa and Morocco. The negatives depict military bases and tents, non-military persons, and scenic shots of landscapes, camels, statuary, and what appear to be ruins or sight-seeing destinations. There are also five 16mm film reels, one 3-inch, three 5-inch, and one 7-inch reel. The films are not available pending digitial preservation.

The collection also contains additional digital images which have not yet been processed.
