" The Super Constellations took three days to reach London [from Australia] and lacked the power or range to dodge most storms. When monsoons or cyclones were encountered, the pilots had no choice but to put on the seat belt signs and bounce through them. Even in normal conditions they flew at a height guaranteed to produce more or less constant turbulence. (Qantas called it, without evident irony, the Kangaroo Route.) It was, by any modern measure, an ordeal. "
