Spey was for many years an important center of the German aviation industry. In 1913, an aviation company began its work, which during World War I produced combat aircraft for the German army. It soon turned out that the plant was too small to meet the expected production, so it was decided to move to Spira a factory hall from the conquered French city of Lille. This hall was called 'Liller Hale' by the residents.
