Ranking the Heaviest Aircraft Ever Flown

Heaviest aircraft ever flown, ranked by maximum takeoff weight: Concorde left the runway at 185 Tonnes and doesn't make the top 50.We ranked 90 aircraft types, from wartime flying boats to today's widebody freighters, by the heaviest weight each one was officially cleared to take off at. Every entry is one specific version, because a stretched or extended-range model often carries far more than the original did. Weights are in metric Tonnes and aren't typical operating loads; for one-off prototypes it's the weight they were designed to fly at.The figures come from manufacturer specifications, air force fact sheets and aviation museum records, as compiled in published reference tables.
