Triangular shaped Fireball in the sky above Mounts Bay - Feb 1, 2014

Could it be visitor from space or perhaps an experimental delta-wing aircraft from Culdrose or beyond?

On the left side of this picture, highlighted by the dark cloud but with its detail obscured, is a bright triangular shape streaking across the sky.

The UFO/Fireball, probably a meteor was snapped by accident and only discovered when Michael Potter reviewed his photographs of Mounts Bay on his computer. via thisiscornwall
