looked like a brain but as large as a mini car..it was covered in a pattern of lights changing colour as an octopus would do,,starting from pale pink to a deeper red

i was walking along when i noticed it silently moving along about seventy five feet off the ground heading west at a thirty degree angle.i thought at first a meteor or something but there was no speed or look of a collision towards the ground. the light i described earlier seemed to have a waxy glow but the more i stared you could see triangular and other patterns each filling with light starting dim and glowing bright.i watched as something dropped off it from what i assume is the back,which looked like a plastic bag on fire.this fell clear of the craft and it proceeded to continue in its slow westerly path,i watched it till it was as a dot in the distance and also saw two aeroplanes approaching which i would assume the pilots must have noticed the object i oserved.

the next morning while walking i saw a helicopter silver in colour and quite large flyin low across the area.its rotars were unusually quiet.maybe they were looking for what dropped off the craft.dont think they found anything.
