UFO Sightings

# Context

This dataset contains over 80,000 reports of UFO sightings over the last century.

# Content

There are two versions of this dataset: scrubbed and complete. The complete data includes entries where the location of the sighting was not found or blank (0.8146%) or have an erroneous or blank time (8.0237%). Since the reports date back to the 20th century, some older data might be obscured. Data contains city, state, time, description, and duration of each sighting.

# Inspiration

* What areas of the country are most likely to have UFO sightings?
* Are there any trends in UFO sightings over time? Do they tend to be clustered or seasonal?
* Do clusters of UFO sightings correlate with landmarks, such as airports or government research centers?
* What are the most common UFO descriptions?
