Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Parachuting is a method of transiting from a high point to Earth with the aid of gravity, involving the control of speed during the descent with the use of a parachute or parachutes. It may involve more or less free-falling (the skydiving segment) which is a period when the parachute has not yet been deployed and the body gradually accelerates to terminal velocity...
Despite the perception of danger, fatalities are relatively rare. In the U.S. during the 1970's, the sport averaged 42.5 fatalities annually. In the 80's, the average dropped to 34.1, and in the 90's, the average decreased to 32.3 deaths per year. Between 2000 and 2009, the average dropped to 25.8 and over the eight years after 2009, the annual average declined to 22.4 fatalities (roughly 0.0075 fatalities per 1,000 jumps). In 2017, members of one organization, the United States Parachute Association (USPA) reported 2,585 skydiving injuries sufficiently severe to require resort to a medical care facility.
In the US and in most of the western world, skydivers are required to carry two parachutes. The reserve parachute must be periodically inspected and re-packed (whether used or not) by a certified parachute rigger (in the US, an FAA certificated parachute rigger every 180 days). Many skydivers use an automatic activation device (AAD) that opens the reserve parachute at a pre-determined altitude if it detects that the skydiver is still in free fall. Depending on the country, AADs are often mandatory for new jumpers, and/or required for all jumpers regardless of their experience level. Some skydivers wear a visual altimeter, and some use audible altimeters fitted to their helmets.
Injuries and fatalities occurring under a fully functional parachute usually happen because the skydiver performed unsafe manoeuvres or made an error in judgement while flying their canopy, typically resulting in a high-speed impact with the ground or other hazards on the ground. One of the most common sources of injury is a low turn under a high-performance canopy and while swooping. Swooping is the advanced discipline of gliding at high-speed parallel to the ground during landing.
Changing wind conditions are another risk factor. In conditions of strong winds and turbulence during hot days, the parachutist can be caught in downdrafts close to the ground. Shifting winds can cause a crosswind or downwind landing which have a higher potential for injury due to the wind speed adding to the landing speed...
