bright white object travelling very fast,trail dissipated after 1 second visible in daylighttravelling from Aberdeen into Peterhead area, 3 of us witnessed a n extremely fast white object soaring through the sky leaving a very short, of same colour, trail which vanished after a second and headed toward the sun, roughly western direction, it was above the clouds but clearly visible by human eye. What was strange was the fact that it was clearly visible in the daylight which could rule out any small comets. This would mean that it was of emmense size with equal brightness as the sun out in space, or was in Earth's atmosphere above the clouds. It couldn't have been an aircraft as it was too fast and left too short a trail.
