The father of a British victim of the Germanwings disaster has urged airlines to take action to look after pilots "properly".
Philip Bramley, whose 28-year-old son Paul was among three Brits killed when the plane crashed into the French Alps, issued a statement saying: "What happened on the morning of the 24th March was the act of a person who at the very least was ill."
"If there was a motive or a reason, we do not want to hear it, it is not relevant," he added.
"What is relevant is this should never happen again - my son and everyone on that plane should not be forgotten, ever. I don't want him to be forgotten, ever."
Bramley, originally from Hull, was studying hotel management in Lucerne, Switzerland at the time of the crash, which left 150 crew and passengers dead.
The plane's co-pilot Andreas Lubitz is believed to have deliberately flown the plane into the mountain range after the Captain was locked out of the cockpit.
Lufthansa, owner of Germanwings, said it had not received medical documents indicating that Lubitz was unfit to fly, after prosecutors discovered a ripped-up sick note relating to the day of the disaster.
