Does Ball lightning account for some UFO sightings?
The phenomenon itself appears to be a pretty controversial one within mainstream science but it refers to luminous, (mostly) spherical objects which vary in size and 'move up, down, sideways or in unpredictable trajectories' - some ball lightning accounts also describe it moving through solid masses of wood or metal without effect and other witnesses report a strange smell like ozone or burning sulphur.
There are some pretty remarkable interviews in the Arthur C. Clarke documentary below with people who claim to have experienced ball lightning and some of their observations do share certain characteristics with UFO testimony:

Many eyewitness accounts describe its movement as having the characteristics of an intelligence guiding it. It often enters structures through windows or doors, though it seems to have no difficulty passing through solid walls. It travels down hallways and up and down stairs and other lines of logical access and egress within structures. It pauses at objects and living things as though observing them. It has been described as similar to remote reconnaissance drones portrayed in science fiction movies.
A diameter of 6-18 inches is the most common size, although reports range from ½ inch up to 50 feet in width. They are luminous and spherical in shape and come in a rainbow of colors, often changing color many times during a single event. They do not seem to do a great deal of harm, although in their exits, they sometimes explode which can cause damage. They have even been sighted in aircraft flying in clear skies and on marine vessels without a cloud in sight.
