An accident probe was under way today into the death of a boy pilot who crashed a single-engined plane into a park. The Cessna crashed into a park in Southend, Essex. Police said no-one on the ground was hurt. Paramedics said the pilot - who was alone in the plane - was declared dead at the scene. The pilot, from Hornchurch, was a 16-year-old who was on only his second solo flight, after he had clocked up 15 hours of flying.
