Limits RegistryU.S. Air Force flight surgeon John Stapp rode a rocket-powered sled to a peak speed of 1,017 km/h (632 mph) at Holloman Air Force Base on December 10, 1954, then decelerated from that speed to a stop in about 1.4 seconds — earning him the nickname 'the fastest man on Earth' and generating data on human tolerance to extreme acceleration used in later aviation and automotive safety design.

The highest speed a human being has voluntarily reached while riding a land vehicle under controlled test conditions, and survived.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
