Scots RAF gunner Corrie McKeague had "slept under bin bags" on a previous night out using them "almost like a blanket" before he vanished on a night out in 2016, an inquest heard.
The hearing into the 23-year-old's death was told the airman was a "nightmare on the drink" and had downed a bottle of red wine in 17 seconds on one occasion.
After a night out in Bury St Edmunds, Suffolk, on September 24, 2016, McKeague disappeared in the early hours of the morning.
