While many aviation museums may display a Boeing B-29 Superfortress or B-17 Flying Fortress or even a Consolidated B-24 Liberator, very few possess a Douglas B-18 (Bolo) bomber. In fact, many aviation enthusiasts have never even heard of, let alone seen, a B-18. There are good reasons for this. Douglas built only 350, and few of those saw active service in World War II. Only six B-18 airframes still exist (and one of those is from a Bolo that crashed in 1941 in Hawaii, where its wreckage remains to this day, exposed to the elements).
The B-18 was based on Douglas’s DC-2by the start of World War II, many B-18s that flew in combat were equipped with magnetic anomaly detectors and used for anti-submarine warfare.
