Skydive is a sport or recreational activity of jumping from an aircraft and falling through the air under a parachute. The sport has its origins in the military use of parachutes for deploying troops, but it evolved into a popular recreational pursuit in the mid-20th century.

The basic equipment for a skydive includes a parachute system, which consists of a main parachute and a reserve parachute, both packed into a container worn on the back. Other essential gear includes a helmet, goggles, and often a jumpsuit. Modern skydivers also commonly use an altimeter to monitor their altitude and an automatic activation device (AAD) which can deploy the reserve parachute if a dangerous altitude is reached too quickly.

Skydivers typically exit an aircraft at altitudes ranging from 8,000 to 15,000 feet. After exiting, they experience a period of freefall, during which they can maneuver and reach speeds of up to 120 miles per hour. The duration of freefall varies depending on altitude and body position, but generally lasts for about 45 to 60 seconds. At a predetermined altitude, the skydiver deploys their parachute, which slows their descent considerably. The parachute ride, also known as canopy flight, allows for steering and a gentle landing.

Safety is paramount in skydiving. Strict training protocols are in place, and first-time jumpers usually undergo an accelerated freefall (AFF) or static-line training program. Tandem skydiving, where a student is attached to an experienced instructor, is a popular entry point for beginners as it requires minimal training. The sport has a dedicated community and various organizations oversee safety standards and competition events worldwide.
