Mystery blimps, or UFAs, (unidentified flying airships) are airships that are unable to be identified, or not registered to be in the area. They are seen back from the first one, in the early 1800s, to today. if you see one that you just can't figure out what it is or what it says, post it here.
Thanks, Blimpest

Unidentified blimp over washington DC. perhaps a terrorist blimp?(since it was seen circling around the white house)
A very very VERY fast blimp seen cruising around area 51. probobly just another secret test aircraft they have going there.
an artists rendition of a weird saucer like ship in 1897. it was going around 10-12 mph., and seemed to have passangers inside. one man said that it exploded, because the hydrogen ignited.
