Stapp, John

American Physician and Researcher 1910-

Colonel John Paul Stapp was a pioneering physician and researcher of the effects of high G forces . From the late 1940s through the early 1960s, he oversaw basic research on the subject of human tolerance to mechanical forces. During this period Stapp worked with human and animal subjects to determine their physical limits, and he played an important part in the high-altitude balloon flights of the ManHigh project, which explored the environment at the edge of space and investigated cosmic rays and their effects on humans.

Stapp is probably best known, however, for his rocket sled rides, during which he was accelerated to 1,017 kilometers per hour (632 miles per hour) and then decelerated to a dead stop in 1.4 seconds. As a result of Stapp's findings, the strength requirement for fighter jet seats was increased because his work showed that a pilot could walk away from crashes when properly protected by harnesses and if his seat does not break loose. Stapp also participated in windblast experiments, flying in jet aircraft at high speeds to determine whether or not it was safe for a pilot to remain with his airplane if the canopy should accidentally blow off. In addition to his pioneering work in aerospace medicine, Stapp coined the phrase "Murphy's Law," which he defined as, "If something can go wrong, it will." After retiring from active service, Stapp served as chairman of the International Space Hall of Fame Commission in New Mexico.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
