Thieves struck the North Atlantic Aviation Museum in Gander this week.
RCMP say a suspect entered the building on the Trans Canada around 3:30 a.m. Monday by breaking into the window of an airplane connected to the building at the rear of the property.
An undisclosed amount of cash was stolen from two donation jars inside.
Surveillance footage captured three people on the property around the time of the break-in, with one person entering the building.
Anyone with information is asked to contact the RCMP or Crime Stoppers.
