Claim:
1. A folding wing comprising: a fixed section; a folding section, the folding section hinged to the fixed section at a hinge line; and a latch system for latching the folding section to the fixed section, the latch system including a plurality of non-backdriveable mechanical latch pin actuators, each non-backdriveable mechanical latch pin actuator comprising a long axis extending through a first end and a second end, each non-backdriveable mechanical latch pin actuator oriented so that the long axis is parallel with the hinge line, each non-backdriveable mechanical latch pin actuator comprising a latch pin, each latch pin configured to move along the long axis between a retracted position and an extended position, each latch pin in the extended position configured to engage the folding section, each non-backdriveable mechanical latch pin actuator further comprising a lock, each lock comprising a lock axis extending through a first side and a second side, each lock oriented so that the lock axis is orthogonal to the long axis, each lock rotatable about the lock axis between an unlocked position and a locked position, each lock configured to create physical interference with its corresponding latch pin in the locked position.
