From David Sky
John Abrahamson’s theory on the origin of ball lightning
(5 February, p 12)
cannot be the whole story.
I have seen ball lightning at the very moment of formation, and the ball I
saw definitely did not form after any strikes to the soil, which Abrahamson says
is necessary. It formed at, and was flung off from, the end of a branch in a
fork of lightning that was discharging between clouds.
