Resurrect deceased pilot
In the pilot selection screen from the control center, highlight the dead pilot's name from the list. Double-click on the name, then double click on the shiny area of the harness buckle on the picture of the pilot in the cockpit. Click on "OK" to freeze the screen. Wait a couple seconds, then click on "OK" to return to the control center. The pilot's status will change from "Deceased" to "Pining for the fjords" to confirm correct code entry.
