Fish Rocket

The device was moving through the sky with a fish-like motion. It was painted orange scales lined with green fading to green scales lined with orange and had great big googly eyes. The tail fin was a beautiful dark green edged in the same orange scales as the head of the fish. There was a bluish glow of exhaust at the gills and a dashed contrail that started a dozen yards behind. The fins (wings) of the the airship were barely visible at the distance I witnessed it.

"Now, thats a UFO," someone said.

"Naw, haven't you ever seen a flying fish," someone else answered.
