i think you'd need to at least use both arms? and land with legs / knees bending and coming to a stop to complete the jump,
instead of sailing down holding on with one arm and just stepping out onto the pavement!,
but - looks cool
for the stunt, maybe a winch has been used (plus harness and the lot),
but wouldnt it be great if tension in a cord could be set to do this
👓👜 (oh, yeh, she does come to a complete stop)
