The search of a landfill site by police looking for missing airman Corrie McKeague is set to be extended.
Suffolk Police resumed their trawl of the Milton site in Cambridgeshire on October 23, focusing on an area known as "cell 22".
It was due to last between four and six weeks but, at the end of the fifth week, police have confirmed it will continue for a few more weeks.
A spokesman said the search was "going well".
"It is recognised that whilst the designated search area remains the same, timescales are not set in stone and subject to many variables.
"It is currently anticipated that the search may progress through to early-mid December. We continue to engage with the family to keep them fully informed.”
Mr McKeague disappeared on a night out in Bury St Edmunds in September 2016. He was based at RAF Honington.
Police fear he may have climbed into a bin in the Horseshoe area of the town which was later collected and the waste taken to Milton.
The landfill search for missing RAF gunner Corrie McKeague is expected to finish by Christmas.
Police investigating the disappearance of RAF gunner Corrie McKeague have "explored all reasonable lines of inquiry", a review has found.
The mother of missing RAF gunner Corrie McKeague is in the Suffolk town of Bury St Edmunds to retrace her son's last known steps
