The site, at Maes Artro Heritage, served as the living quarters for the adjacent RAF Llanbedr air base during WWII. The base opened in 1941 as a training and rest camp for active squadrons. Since then, the base has witnessed much violent loss of life as unexplained crashes and accidents were frequent.

NIGHT 1 of the 3 night investigation began with a Seance involving Yvette, Derek, Stuart, Cath and Ciarán (in observation). Derek became possessed by a Squadron Leader called Ian, who seemed to be aware that he'd passed away, while he and his colleague were there to visit the Most Haunted team. Phenomena included unexplained cold blasts of air and the occasional scraping noise and bangs on the roof. As the evening progressed the team moved on to the old shower block, where Yvette and Derek felt they heard what sounded like a firm footstep from behind. Leaving Cath to take up a solo-vigil, the team moved on to the Officers Mess, where they heard what sounded like a chair being dragged and Derek connected with a spirit called "Mack". The evening concluded with a table-tipping experiment which brought about some interesting results, as the table appeared to tip when the team asked questions to the apparent Spirits who were present.
NIGHT 2 began in the old shower block where a number of tapping sounds were captured coming from the back of the exhibition aircraft while Derek connected with a Norweigen pilot called Johannson who regularly visited the location to vent his anger at his superior officer. Stuart undertook a solo vigil in the old projector room where he experiened drastic falls in temperature. Moving on to the sealed experiment in the 1940's Room, the team are convinced they hear the sound of a man laughing during Derek's connection with Flight Leuitenant Geoffrey Page. Derek then appears to be possessed by Squadron Leader James MacLoughlin who informs the team that 17 spirits were present on the base, one of which had touched the coins during the 'Sealed Room' experiment. The team conclude the night at the Morgue, where further cold spots were reported, while Derek and Psychic Artist Brian Shepard picked up on a group of angry German prisoners of war.
NIGHT 3 commenced with an investigation of the air-raid shelter, where it appeared little occured however during this time a conversation could clearly be heard, assumed to be someone outside. After checking it appeared that nobody was actually talking. Karl was left to take up the vigil on his own where he detects sounds, presences and the smell of leather, while the team move on to a Timeslip experiment where the 1940's were recreated in the officers mess. During this a mass of active spirits were picked up on by Derek and Brian, while the sound of a bottle clanging is clearly heard. Back in the hub the team discuss the results of the sealed room experiment from Day 1 where footsteps were caught on the dictaphone. The crew then take part in a seance in the projector room. Asking questions of the spirit the glass on the table continually appears to move in response. The team then experience sharp drops in temperature while the glass began spinning dramatically. The team then move onto a Table-Tipping experiment where the table (on casters) spins continuously in reponse to questions.
