43. Three-Person Rocket Launch
Build the circuit above. In this circuit, pretend the lamp (76) and the LED (69) are a rocket. To launch the rocket the
switch (62) must be ON, AND the press switch (61) must be ON, AND the reed switch (83) must be turned ON with the
magnet (7). Systems like this are used to prevent accidental rocket launching by having the switches placed far enough
apart that it requires three people to turn them on simultaneously.
