See SWNS story SWUFO; Ethan Hodge, 23, was out with his pal around 9pm at night when they spotted an unusual light whizzing around. It swirled around the sky before vanishing into thin air and then came back into view as what Ethan described as a "ring of blue fire". He filmed the strange encounter last Monday evening over Siston Common, near Mangotsfield, Bristol on his Samsung Galaxy s7 edge phone.
