This is from a dataset with some 80k or so sightings. I narrowed to cigar shaped craft (about 7,000), and created this word cloud. Then I created another word cloud for disk-shaped objects. Looks pretty similar tbh, I struggled to tell the difference. Then I created a "difference cloud", to highlight the differences between them. Cigar observations mention wings way more than disc ones (duh), and disc ones mention colors, and adjectives like "hovered" a lot more. This isn't polished of course...
