Harmony Angel is the code name that the Spectrum Organisation has assigned to Chan Kwan, the former owner and proprietor of Peking Taxi Service, a Tokyo, Japan-based air-taxi service that her Mainland China-born father had established and passed on to her at his death. Before joining Spectrum, Kwan held a world record for fastest nonstop aerial circumnavigation of Earth; she had had to abort a previous attempt she had made to set that record to rescue oilmen from a burning derrick in the middle of the ocean.
