Not sure if you're interested, but the risk of base jumping comes from the fact that you're starting from zero airspeed, which means that all of your "flight control surfaces" (arms, legs, torso, etc.) that skydivers use to re-position themselves during falling are useless. There's not enough air flowing across your limbs to produce any usable force. This means that there's a risk you're not in the necessary deploy position when the critical throw/survive moment arrives, and you carry an increase risk of not surviving.
