- To expand a bit, "preset" means "preset at firing time". The fuzes
- were adjustable, and set to the predicted (radar, optical) altitude,
- or, rather, the predictied time of flight to reach that altitude.
- Originally done by hand, by mid WWII, much of this had been semi
- automated, with analog computers driven from the radar (optical)
- inputs, as much as possible. The fuzed shell was poked into an
- opening, and the machine set the delay.

- As to the ffect of ground fire, there were published reports, between WWI and
- WWII, based on small scale actions (Central/Sout American wars, for one). These
- argued that the effect of strafing fire, on trained troops was minimal, and that
- disciplined return fire could, at least, keep the raider up. How accurate,
- how applicable to other conflicts, and how applicable to more modern weapons
- systems, is left as an exercise for the student....
