Astronauts are provided with survival kits due to the difficulty of predicting where a spacecraft will land on its return to earth, especially in the case of an equipment failure. In early US space flights, the kit was optimised for survival at sea; the one provided for John Glenn on the first American space flight in Friendship 7 contained "a life raft, pocket knife, signaling mirror, shark repellent, seawater desalting tablets, sunscreen, soap, first aid kit, and other items".[5] A survival kit was provided for the Apollo program which was "...designed to provide a 48-hour postlanding (water or land) survival capability for three crewmen between 40 degrees North and South latitudes".[6] It contained "a survival radio, a survival light assembly, desalter kits, a machete, sunglasses, water cans, sun lotion, a blanket, a pocket knife, netting and foam pads".[7]
Prioritizing your needs can best be determined by considering how long you can go without one of your needs before you risk physical harm or death. For instance, if it is spring or summer, staying warm is not a huge priority (unless it is raining and you have no shelter), because the risk of hypothermia during daytime hours is low. Consider this same factor in the wintertime and that fact that frostbite and hypothermia can set in within a matter of hours, and suddenly finding a warm place to stay and building a fire is of paramount importance.

The Missouri Information Analysis Center (MIAC) issued on February 20, 2009 a report intended for law enforcement personnel only entitled "The Modern Militia Movement," which described common symbols and media, including political bumper stickers, associated with militia members and domestic terrorists. The report appeared March 13, 2009 on WikiLeaks[89] and a controversy ensued. It was claimed that the report was derived purely from publicly available trend data on militias.[90] However, because the report included political profiling, on March 23, 2009 an apology letter was issued, explaining that the report would be edited to remove the inclusion of certain components.[91] On March 25, 2009 MIAC was ordered to cease distribution of the report.[92]
