Henry Allingham will be 110 on 6 June

Two tornadoes from 31 squadron are to fly over the Grand Hotel in Eastbourne for the anniversary on Tuesday.

Henry Allingham, a World War I air service veteran, lived in the town after retiring, but recently moved to a care home near Brighton.

"He really does marvel at the fact he has reached the age he has," said close friend, Denis Goodwin.

"It's going to be a tremendous day for Henry and I'm sure he will enjoy it."

Mr Allingham will be joined by senior figures in the RAF for the fly-past.

He will later have a private lunch with family members from the US.

He served as a mechanic with the Royal Naval Air Service during the war, before transferring to the newly-created RAF.

He is the last remaining founder member of the RAF and the only remaining survivor of the battle of Jutland.

He has five grandchildren and 12 great grandchildren.

In March, Mr Allingham was given the freedom of Eastbourne, where he had lived since the 1960s.

Three weeks ago he moved to St Dunstan's, a care home for ex-service personnel, in Ovingdean.
