Myself, my partner and mother (she doesnâ€™t want to be named) were sitting in her garden celebrating her birthday, it was late afternoon, early evening. the weather was humid and over cast. my partner suddenly said â€œwhatâ€™s that?Â€� we glanced to where he was pointing, way in the distance we saw a black object moving across the sky towards us.. as it got closer we could see that it was twisting but we couldnâ€™t accurately make out the shape. we continued to watch it move across the sky closer to where we were sitting. we started to speculate that it was maybe a balloon.. or a light air craft, which it certainly wasnâ€™t, no wings, no engine, no sound. it continued moving across the sky twisting but appearing to stay at the same altitude at a steady pace. as it twisted the sun shone onto one side and it reflected, looking a silvery colour. i started to film it on my iphone travel across the sky whilst we got some binoculars. by the time we got the binoculars the object was very far away and i couldnâ€™t make out any details through them. the object continued on, not dropping not rising on a trajectory until it went out of site. we all had a mixture of thoughts, a balloon a light air craft.. but it looked very very strange, i immediately thought itâ€™s a ufo. iâ€™d be interested to know what others think.. is it a balloon..?
