Resembling ballet dancers at the exercise barre, firefighter applicants watch their competitors sweat and groan through physical fitness tests, which included hanging bent-armed from a horizontal bar, on Oct. 10, 1978. Nearly 5,000 people, including about 100 women, were tested at the Chicago Fire Academy in Chicago. Only the top 300 are expected to be hired.
