be programmed for survival. If there is an in-flight abort that requires returning to the ground from halfway to orbit, the pilot must turn a rotary switch on the console to choose between returning to Florida and landing in Senegal. The switch controls loading of data and routines into the computers. This was required because the software for flying the Shuttle runs ~500k of code, and the computers can only handle 64k. The decision routines for which part of the software to swap in were left in the pilots head.
