London, Mar 30 (UNI) The pilot of the plane which crashed into the English Channel with footballer Emiliano Sala on board, was not qualified to fly at night, BBC Wales understands.
David Ibbotson is thought to have been colour-blind, which prevents pilots from flying at night.
Footballer Sala, 28, died when the plane carrying him from Nantes to Cardiff crashed late on 21 January.
