Airbus's A320, whose program was launched in 1984, was designed as a narrow-body, short- to medium-range aircraft that incorporated numerous technical innovations, most notably fly-by-wire (electric rather than mechanically linked), computer-based flight controls.
Most existing vehicle launched deployable bridges (also known as assault bridges or mobile bridges) take the form of a simply supported beam and require mechanically complex deployment sequences.
But they then considered the Zeus system itself, and noted that its use of mechanically steered radars, with one radar per missile, meant that Zeus could only launch a small number of missiles at once.
Reappraisal of the proportions, scaling and morphology of giant pterosaur fossils suggests that bird and pterosaur wing structure, gross anatomy and launch kinematics are too different to be considered mechanically interchangeable.
