History
Background and predecessors
The 311th Human Systems Wings's origins can be traced to 19 January 1918, when the United States Army Air Service formed the Medical Research Laboratory at Hazelhurst Field, on Long Island, New York..
Hazelhurst was selected as the most important Army flying school on the east coast. Initial work at Hazelhurst included experiments with low pressure chambers and development of psychological profile tests. When Hazlehurst closed at the end of World War I, the laboratory moved to nearby Mitchel Field, where it combined with the School for Flight Surgeons. In 1922, the laboratory and school became School of Aviation Medicine and the focus became training flight surgeons, with experimentation limited to ways to improve their training.
This brief starts where responsible research should: with the source description of “311th Human Systems Wing” as inactive unit in the U.S. Air Force. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as inactive unit in the U.S. Air Force. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jan 25, 2026. The linked authority identifier is Q4634686. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1918, 1946, 1957 and 1961.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
