The hatches between pods are controlled by a button in the center of each pod. While a control button is depressed, all hatches with that letter are open; but as soon as the button is released, those hatches close. A person cannot simultaneously depress a button and move through a hatch. Can our three space scientists make it from the Airlock to the Control Room? On the left is an example (and its solution).
