Astronauts carry passports and other documentation on shuttle flights?

Shuttle Down was a novel that portrayed the Space Shuttle being forced to make an emergency landing at the most remote airport in the world on Easter Island.  It then went on to discuss how to repair and fly the shuttle back to the United States, which was made difficult by the size of the airport and the lack of documentation on the part of the astronauts (after all, who carries their wallets into outer space?).

"In real life, and shortly after publication of this book, the United States paid the Chilean Government to improve the facilities at Mataveri International Airport on Rapa Nui in case of just such an emergency, and the airport now has a relatively long runway.^{[citation needed]}

In addition, astronauts now carry passports and other documents, including traveller's cheques, in case of emergency landings.^{[citation needed]"}

^{Do I believe that?  Maybe not.  But still a fun thought nonetheless.}
