theories Conspiracy theories and urban legends spread through the internet since the 2000s suggest that the brace position is ineffective at stopping injuries or deaths, and that the actual intention behind its adoption is to kill passengers in crashes, either to ensure a painless death, preserve their remains, or to avoid lawsuits against the airline. Such claims have been debunked by the MythBusters, by fact-checking website Snopes and by aviation professionals.
