Police investigating the disappearance of airman Corrie McKeague have resumed the search of a landfill site.
The examination of the area was paused over the weekend after the excavator broke down.
A search team investigating the case has already trawled through 60 tonnes of waste at the site in Milton, near Cambridge.
It could take the team of eight trained search officers up to 10 weeks to sift through rubbish up to eight metres deep, covering around 920 square metres of the dump.
A bin lorry found in the area where airman Corrie Mckeague was last seen weighed more than first thought, police have said.
His mother, Nicola Urquhart, says it's dashed her hopes of finding her son alive.
There's been no trace of the RAF gunner since he disappeared after a night out in Bury St Edmunds on the 24th September last year.
