Brighton's i360 is celebrating its first year of business today with half a million people visiting the attraction.
However, the visitor numbers fall short of the 700,000 originally predicted.
British Airways i360 says it's kept up with its loan repayments to the council and some of the profits will help restore Madeira Terraces on the seafront.
The company says it has created 150 jobs, given 39,000 free tickets to the city's children and held five weddings.
There will be a special flight later with guests on board being welcomed with drinks and cake.
