More than 90 people searched through woods, heath and marshland for missing airman Corrie McKeague on Sunday.
The third public search for the 23-year-old focused on Cavenham Heath and an area of Mildenhall Woods but nothing was found to solve the mystery of what happened to the RAF Honington gunner.
In total there were 105 people involved in the operation, which included 35 members of the public who volunteered to help following an appeal by Corrie’s mother Nicola Urquhart.
There were also 60 searchers from Suffolk Lowland Search and Rescue (SULSAR) as well as Norfolk, Essex and Cambridgeshire Search and Rescue.
They covered six to seven square kilometres in about seven hours.
Nicola said: “It’s been five months now since Corrie’s gone missing.
“I can’t describe how I’m feeling. We’re just getting by, each day as it comes.”
With Corrie’s brothers Darroch and Makeyan joining her in the search, she said the strength they get from each other is ‘immense’ and the support they receive from the public helps them ‘get through’.
Nicola said taking part in the search was ‘incredibly difficult’ but it is something they had to do.
“We can’t just walk about feeling sorry for ourselves. That’s not who we are. We’ve got to do something constructive about trying to find him,” she added.
Andy King, chairman and search manager with SULSAR, said the search was based on a possibility that Corrie may have been hit by a car and his body dumped in a remote area.
He praised the public’s ‘fantastic’ contribution to the search and said some of them now intended to join SULSAR on a full time basis.
Corrie disappeared on September 24 after a night out in Bury St Edmunds.
He was last seen at 3.25am in Brentgovel Street.
Police are due to carry out a search at a landfill site, in Milton, Cambridgeshire, as part of their investigation into his disappearance.
Anyone with information about his disappearance should call Suffolk Police on 01473 782019.
