1. A method for collapsing fabric-covered wings of an aircraft comprising:
(a) providing an aircraft including a first wing assembly having at least one first rib assembly supported by a first wing spar, and a second wing assembly having at least one second rib assembly supported by a second wing spar;
(b) covering the first wing assembly with a first wing fabric, and covering the second wing assembly with a second wing fabric;
(c) coupling the first wing fabric to the at least one first rib assembly with at least one fabric-coupling member;
(d) coupling the second wing fabric to the at least one second rib assembly with at least one fabric-coupling member;
(e) pivoting at least one front wing rib of the at least one first rib assembly in a first direction;
(f) pivoting at least one rear wing rib of the at least one first rib assembly in a second direction which is a direction opposite to the first direction;
