Hi Folks this has nothing to do with Brum although I did work for David Charles Construction in the 70`s, I was about 19yrs old an apprentice for a company in St.Ives Cambridgeshire. It was a hot afternoon & thunder rolled around us but it was dry no rain, then small spherical transparent balls shot from the sky all around myself & my work mate. They hit the ground silently then flew of across the yard whilst all the time thunder rolled around above but no rain, my work mate said they where thunderballs yet I can find no information about them does anyone here know anything about them please?
