There were THREE bright orange lights coming high from the south over Epping forest they then stopped high above me, approx 200 feet to the North West of my location...There they seemed to one by one dissapear.

no but they were definately powered as i could see a trail of flame like emmision short behind each of them.

I saw them by chance looking out over the forest as i was checking the weather for a bike ride tommorow{saturday 21st March} they were moving about the same speed as the usual aircraft but they seemed purposefull and gracefull somehow. They had no lights on them other than the incandecent orange glowing and a short tail...I couldnt say they were flares as i watched them travel at least ten to fifteen miles across the forest toward me. I hope this has been of some help but it was definitely something strange.
