Like the Kennedy assassination, the death of Manfred von Richthofen is clouded by dozens of often conflicting eyewitness accounts and has inspired a mountain of speculative theories.
"Who Killed the Red Baron?" is based partly on a notable recent investigation of those theories, The Red Baron's Last Flight, by Norman Franks and Alan Bennett.
Another important recent book, The Many Deaths of the Red Baron, by Frank McGuire, surveys the literature supporting the competing claims.
