Sensitive Note

When referring to a black person, the term spook dates back to the 1940s. It is used with disparaging intent and is perceived as highly insulting. Black pilots who trained at Tuskegee Institute during World War II were called the Spookwaffe. Some sources say that black pilots reclaimed this derogatory nickname as a self-referential term of pride.
