Friend worked on the F16, Fly-By-Wire control system and computer. It is an Analog Computer. Turns out, digits were simply not fast enough and powerful (number crunching) enough to deal with the real time requirements of fly-by-wire at that place in time.
Some how, the whole analog computing ideal has been set aside and forgotten by many binary computer centric folks.

In the Navy in '65 I was treated to a visit inside an F4 Phantom simulator trailor. That was one big analog electromechanical maise on wheels. Analog computers laid the ground work for digital to take off from.
