I saw an object hanging in the sky. I was driving on the A2 from Dover north towards Canterbury, it was about 3 miles from the Lydden turn off. I saw what looked like a bright star at first, which was odd as it was still light with light cloud cover, it was bright, sun was just going down. I saw this object which was stationary, as I got closer the shape changed, it appeared cigar shaped, but was segmented with what appeared to be windows. It looked like a plane without wings, it did not move, It was in view for about 5 mins, then it just disappeared as if switching a light off. The road was quite busy at this time so it must have been seen by others.
