The document summarizes the issues surrounding the opening of Heathrow Terminal 5 in March 2008. Key problems included the failure of the baggage handling system which caused thousands of bags to be delayed. This was due to insufficient testing of the system under high loads and communication failures between BA and BAA. Over 28,000 bags were left in temporary storage over the opening weekend, cancelling hundreds of flights and delaying many more. Willie Walsh acknowledged corners were cut on testing and staff training, and that they did not fully implement lessons from previous openings.
