A man's death on a Six Flags roller coaster in Georgia has raised questions about ride safety and regulation. On Monday, a 42-year-old man was thrown from his seat on the Goliath ride, striking other patrons before landing below. In the U.S., state governments regulate amusement parks, not the federal government. Deadly roller coaster accidents are rare, and some experts say the industry has multiple safety checks and adhere to standards set worldwide. Some call for more federal oversight to ensure consistent safety standards across states.
