What space, submarines and polar research teach about teamwork

If you are fed up with the other people on your team, remember this: it could be so much worse. Butch Wilmore and Suni Williams, two American astronauts, returned to Earth on March 18th after a planned days-long mission to the International Space Station turned into a nine-month stay. At the SANAE IV research station in Antarctica, reports have emerged of assault, death threats and intimidation among a team of South African scientists who arrived there in February; they are due to leave the base only in December. Submariners on Britain’s nuclear-armed subs can be at sea for six months or more.
