The article brings a spreadsheet model of J. W. Kittinger’s legendary jump from the stratosphere performed in 1960. The most likely solution to the fall is presented. Some data published about the fall turned out to be contradictory. The discrepancies are pointed out. The main results are that (1) it is impossible that Kittinger reached supersonic speed and (2) it is possible that he reached the published maximum speed of 274 m/s but not at the published altitude and not if he used his parachute system in the published way.
