Construction on Heathrow's terminal five has been completed six months ahead of the March 27th opening.
The new terminal, which will see 30 million passengers-a-year pass through its doors is just undergoing the final fitting and testing.
As part of the preparations for real passengers, terminal five is going through its proving trials to ensure everything is in working order, including the 18 kilometres of track for the baggage system.
Not only is the size of the terminal unique in the UK - it is big enough to fit 500 football pitches - but it also includes new security technology.
Before getting on board a plane, passengers will have their photograph and fingerprints taken at passport control before passing their hand luggage through advanced X-ray machines.
Then at the departure gate, their fingerprints are scanned and, if there is a difference between the last scan and the first one, security operatives are notified.
Construction on the terminal was safer than expected, there was one fatality compared to the five that had been predicted.
