Move to the back of the bus (but not the airplane)

“In Charlotte and the rest of the Jim Crow South [during World War II], inter-city travelers (whether by bus, train or airplane) were always segregated by race. On trains Negroes were segregated into separate cars, and on buses they were segregated at the back.

“On airplanes, however, Negroes had to sit in the front seats: the back seats were reserved for whites because, at the time, the back of the airplane was considered the safest place.”
