This cache is located close to the Prospect Shopping Centre near a statue of pioneering aviator Amy Johnson, who was born in the city.
Johnson is famous for such feats as being the first woman to fly solo from Britain to Australia and the first, along with a co-pilot, to fly from London to Moscow in one day. She also broke several existing records such as Britain to South Africa (twice, after her first record was itself broken), Japan, and India.
She died in 1941 while transporting planes for the RAF. Conflicting reports state that she was either forced to bail out over the Thames Estuary during bad weather or that she was shot down by British anti-aircraft guns for failing to give the correct identification signal. Her body was never found.
Aside from the statue, you can also see the 'a moth for Amy' trail which consists of 59 decorated moths placed around the city. There are also tributes to her in several other cities around the world.
This can be a very busy area hence the difficulty level.
