Abstract: A jumpsuit for controlled freefalling in which the suit is provided with enlarged expansible wing portions between the sleeve portions and the body portion of the jumpsuit and a wing extender line which extends from each hand of the wearer through each corresponding sleeve portion and inside the wing portion to the waist area of the jumpsuit, where both extender lines pass through a control member. The control member is provided with means for pulling both extender lines away from the suit in order to expand the wing portions when the arms are extended, and are also provided with latch means for latching the extender lines in the expanded positions. Moreover, the control member is further provided with means for rapidly unlatching the latch means to permit free passage of the extender lines back into the suit in order to allow the expansible wing portions to retract toward the wearer's armpits.
