The National Museum of the Mighty Eighth Air Force, Pooler, GA, has raised $18.3 million as part of its “Maximum Effort” capital campaign, moving the project into its third and final phase of improvements. The campaign, which began with a $4.5 million allocation from Chatham County’s SPLOST 7 referendum, originally set out to raise $10 million. Over the past five years, the effort has grown well beyond that target, supported by 275 individual contributions. Museum officials say the total now stands at more than $18 million.
