Source-derived summary

BASE jumping () is the activity of jumping from fixed objects, using a parachute to descend to the ground. BASE is an acronym that stands for four categories of fixed objects from which one can jump: buildings, antennas (referring to radio masts), spans (bridges) and earth (cliffs). Participants jump from a fixed object such as a cliff and, after an optional freefall delay, deploy a parachute to slow their descent and land. A popular form of BASE jumping is wingsuit BASE jumping.

In contrast to other forms of parachuting, such as skydiving from airplanes, BASE jumps are performed from fixed objects that are generally at much lower altitudes, and BASE jumpers only carry one parachute.

BASE jumping is significantly more hazardous than other forms of parachuting and is widely considered to be one of the most dangerous extreme sports.

History

Precursors

Fausto Veranzio is widely believed to have been the first person to build and test a parachute, by jumping from St Mark's Campanile in Venice in 1617 when he was more than 65 years old. However these and other sporadic incidents were one-time experiments, not a systematic pursuit of a new form of parachuting.

Birth of BASE jumping

Precursors to the activity date back hundreds of years. In 1966 Michael Pelkey and Brian Schubert jumped from El Capitan in Yosemite National Park.

Editorial summary

“BASE jumping” enters the record as activity where participants jump from fixed objects and use a parachute to break their fall. Crown Archives preserves that source wording while asking what BASE, jumping and activity can confirm, complicate or overturn.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1617, 1966—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around BASE, jumping and activity.
Editorial analysis

Why this record matters

“BASE jumping” is worth following because a concise public description often conceals a longer documentary argument. Here, BASE, jumping and activity provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 8, 2026. The linked authority identifier is Q809831. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1617 and 1966.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
