Abstract: Disclosed is a telescoping wing locking system for use in aircraft having wings that collapse and expand in a telescoping fashion, such as aircraft designed for use on roadways. Companion wing segments are locked in place when gas is supplied to inflate a bladder located between overlapping sections of the wing segments. Wing segments are unlocked when gas is removed from the bladder so that it deflates and allows the wing segments to be moved relative to each other. The wing segments may be locked in any position relative to each other in which a section of one segment overlaps a section of the neighboring segment with the bladder between.
