It has been Southport (seaside resort in Lancashire - how apt!) Airshow and this old girl flew from Hamilton, Ontario, under her own steam, to Britain to appear with her British sister at the show.
They are the only two remaining airworthy Avro Lancasters in operation.
In 1944 my mother was transferred from the munitions factory to Rolls Royce in Derby to work on Merlin aircraft engines so she might have worked on the engines of this one. The Lancasters where designed and made by A.V. Roe (aka AVRO) at Woodford in Cheshire, about 7 miles from where I live.
You have to hand it to those old men and women, they knew how to build aircraft! And it's great that there are still younger people keen to keep them going.
About now (4.15pm Sunday) the old girl will be doing a fly-past at the Derwent reservoir in Derbyshire, where Lancaster's practised for the Dambuster's raid in 1943.
