Pilot Officer Harold Rosofsky was 26-years-old when he died in a plane crash in Suffolk in 1939.
The Commonwealth War Graves Commission could not get in touch with his family to gather details of how he should have been buried, so he was given a gravestone marked with a Christian cross.
It's believed to be the first case of its kind.
The mistake was only realised in 2012, when relatives were visiting the graveyard of All Saints and Saint Andrew, Honington with Sapiston.
QC and chancellor of the diocese of St Edmundsbury and Ipswich, David Etherington, says the wish should be honoured, despite it being an exception to the standard rule that only Christian symbols be allowed in Anglican churchyards.
