About Delaware UAP sightings

Delaware's small geographic area and population make its 743 reported sightings significant on a per-capita basis. Dover Air Force Base — home to Air Mobility Command's largest wing — is a key strategic installation that generates constant heavy aircraft activity over the state.

The Delaware Bay and Atlantic coastal waters produce marine sighting reports. The state's position in the densely populated Northeast Corridor means observers are sophisticated and more likely to report anomalous rather than conventional aircraft.

Dover AFB's role in repatriating fallen military personnel generates significant C-17 activity that is publicly known, but the base also conducts classified operations that may contribute to anomalous observations.
