Rolls-Royce Trent XWB engines, one of the most efficient flying in the world today, have powered the Airbus A350 XWB aircraft to the skies for the first time Friday morning.
The aircraft took off from Toulouse, France, at 10am local time.
Tony Wood, President - Aerospace, Rolls-Royce, said: "We congratulate Airbus on today's huge achievement and look forward to supporting the A350 XWB to a successful entry into service and beyond. Our own employees are very proud to have delivered a global engine programme that has achieved new levels of efficiency."
UK Deputy Prime Minister Nick Clegg said: "The A350-XWB's maiden flight is significant for Airbus, Rolls-Royce and the aerospace industry - it shows that government's long-term Aerospace Industrial Strategy is the right approach to ensure the UK remains Europe's number one aerospace manufacturer.
"This is a big moment for the aerospace industry and the aircraft's first flight marks the continued commitment to innovation and excellence, contributing to stable economic growth and jobs."
