Luton Airport has been found guilty of safety breaches over the death of a pensioner crushed by a lorry in 2009.
London Luton Airport Operations Ltd and C-T Aviation Solutions had denied the charges but were convicted at Luton Crown Court on Monday after a six-week trial.
Mary Whiting, 78, of Norwich, had just returned from a family holiday in May 2009 when she was hit by a truck being driven by Rossano Casagrande, 50, of Peterborough.
He was found not guilty in 2010 of causing death by careless driving.
A hearing last year heard the crossing was on airport-owned land and did not conform to regulations that apply to public roads.
It has since been modified.
An airport spokesman said today: “The wellbeing and safety of all visitors to the airport has always been, and continues to be, of central importance to us.”
