An open-top bus parade has been held in Derby to celebrate the success of an important British export.
Crowds were on hand to cheer the designers of the new Rolls-Royce's Trent XWB engine as the first one was delivered to Toulouse in France.
The firm hopes to produce 4,000 of the aeroplane engines.
