The funeral of David Traill.
On 29 November 2013, a police helicopter crashed onto the Clutha pub in central Glasgow.
The cause - two vital fuel switches were turned off during the flight.
Mystery of turned off fuel flow switches in Clutha helicopter
Why would an experienced pilot knowingly turn them off?
The switches, which control the flow of fuel to the engines, are both supposed to be on throughout a flight.
Why was autorotation - a form of emergency landing which pilots perform in the event of double engine failure - not achieved?
Ten people died in the incident, all three on board and seven people on the ground.
The pilot who died in the crash, Captain David Traill, 51, was a former RAF pilot and instructor.
He is thought to have been one of Prince William's flight instructors.
The helicopter crashed through the flat roof of the Clutha Vaults at 10.22pm on 29 November 2013.
