Overview

• Yang Guang and Tian Tian, the UK's only giant pandas, are returning to China after 12 years at Edinburgh Zoo.
• The pandas are traveling in specially designed metal crates on a chartered plane, described as 'first-class bedroom accommodation'.
• The pandas' journey includes a handover of responsibility for their welfare from the UK to China at the halfway point of the flight.
• Despite efforts, the pandas did not produce a cub during their stay at the zoo, which was the initial aim of their transfer to the UK.
• The pandas will undergo quarantine and health checks upon their arrival in China, where they will live at a sanctuary in Sichuan province's capital, Chengdu.
