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).[1][2] 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.
TIL.
So technically, if I jump from the roof of my garden shed, it is BASE jumping. Free solo if I omit the parachute. Or is it mandatory to use one?
Get a tiny one from those army men toys, glue it to your shoulder. BASE jump accomplished!
Bonus points if you go inside and listen to Ace of Base afterwards.
