Base jumping is an extreme sport that involves jumping from fixed objects, such as buildings, antennas, spans (bridges), and earth (cliffs). Participants use a parachute to break their fall, allowing them to land safely on the ground. The term "BASE" is an acronym that represents the four categories of jump sites. Jumpers typically wear specialized gear, including a parachute and a jumpsuit, to enhance safety and performance. Base jumping is considered more dangerous than traditional skydiving due to the lower altitudes and shorter free-fall times, which leave less room for error in deploying the parachute.
