UFO sightings in Delaware
No single case dominates Delaware's record. Sightings are logged steadily through the national reporting networks and cluster along the I-95 corridor and the coast. Report what you see with the time and direction, and rule out the usual causes first.
Saw something over Delaware?
Most strange lights have an ordinary cause. Run the identifier: seven questions and the three most likely explanations, from a Starlink train to Venus to a drone, each with how to confirm it.
Note the exact time, the compass direction, the height above the horizon, how long it lasted and how it moved. Check a flight tracker and a satellite app before deciding it is unexplained.
File it. The National UFO Reporting Center and MUFON take reports from every US state, Delaware included, and their databases are where the per-state counts actually live.

The famous cases above follow the public record; XenoAtlas documents claims and their explanations and takes no position on whether any involved non-human contact. Per-state sighting counts are maintained by NUFORC and MUFON. For the big cases on a map, see the case files.
