The Duke of Gloucester is due to open a restored building in South Gloucestershire that played a key role in the history of aerospace.
Pegasus House in Filton was the original headquarters of the Bristol Aeroplane company. It hosted visits from royalty and even Cary Grant before it went out of use in the 1990s. It will house 300 Airbus staff after being renovated as part of a £70m investment programme.
Today's event will have a 1930s feel to it, celebrating the history of the building.
The first test flight of the new Airbus A350 airliner takes place this morning [Friday] at Toulouse in France. Much of it was designed at Filton near Bristol.
Employees who helped to build the state-of-the-art aircraft will be able to watch the take-off live on giant screens at their site.
Rolls-Royce will donate a million pounds to towards the establishment of the Bristol Aerospace Centre at Filton. It will also supply a number of heritage engines to the exhibition, including the Olympus 593, which powered Concorde.
It will be displayed alongside Concorde 216, the last of the super-sonic planes to fly.
A preservation group dedicated to saving Concorde has reacted angrily to news that its offer to house the historic aircraft has been turned down.
The Save Concorde group says it could build a basic hanger far quicker and cheaper than current proposals for a museum at Filton, where the last Concorde to fly has been standing outdoors for the past ten years.
Instead the owners, British Airways, are backing a rival bid for a £12 million scheme now the subject of a revised application for lottery money.
Nick Clegg will visit Bristol today to announce new investment in the aerospace industry.
The Deputy Prime Minister will be given a tour of the Airbus site in Filton and host a discussion with workers from across the aerospace sector.
A century of flight came to an end at Filton Airfield today. The airstrip north of Bristol is regarded by many as the birthplace of British aviation.
It is famous for producing Concorde - the world's first supersonic passenger plane.
But over the decades workers at Filton also created world war bombers and giant airliners, making the city one of the most important aeronautical centres in the country.
Robert Murphy reports:
The last commercial flight has taken off from Filton's famous airfield. It happened just before midday. The airfield will close completely on New Year's Eve after more than one hundred years in operation.
Today owners BAE said it had signed a deal with a property developer for the land. The closure went ahead despite a big campaign by many Bristolians.
