The document discusses the Heathrow Terminal 5 project, including its history, vision, organizations involved, and initial operations. When Terminal 5 opened in March 2008, it experienced significant issues with its baggage system that prevented it from operating as intended. British Airways blamed staff unfamiliarity with the new systems, while BAA claimed the system worked but was overwhelmed by too many bags due to lack of BA staff. The failures highlighted problems with the pre-opening testing and training that was conducted.
