Dukedom of Buckingham. In 1521, however, the third Duke, Edward Stafford was beheaded by Henry VIII and the Forest reverted to the Crown. After Henry's death, Edward VI granted the forest to Sir Richard Rich. In 1592 the Rich family sold their interest in the forest to Lord Morley and in 1612 sold the rest of their Hatfield estate, including the lordship of the manor to Sir Francis Barrington. This resulted in a succession of disputes over ownership and rights in the forest for the next 200 years. In 1729 it was purchased by the Houblon family. They were a wealthy family, originally from Lille, and included John Houblon who had been the first Governor of the Bank of England in 1694. While leaving the traditional woodland management techniques little changed, the Houblons probably sought the help of Capability Brown. As a result, the lake was created and exotic trees planted (i.e. trees not native to Essex). A picnic house was constructed overlooking the lake, and in 1759 it was decorated using British and tropical shells by 17-year-old Laetitia Houblon (1742–1828); this Shell House can still be visited today. The forest remained in the hands of the Houblon family until 1923, when Edward North Buxton bought the Forest from his deathbed and gave it to the National Trust. Air crashes On 20 October 1987, Hastingwood Hotels Ltd, Cessna 421B Golden Eagle (G-HAST) crashed into the forest after taking off from London Stansted Airport, the pilot and Five passengers died. On 22 December 1999, Korean Air Cargo Flight 8509 crashed into the forest after taking off from London Stansted Airport. The plane, a Boeing 747-200F, narrowly missed striking houses in the area. All four crew members on board died on impact. Woodland management Hatfield Forest contained woodland long before it became a royal forest. This has been managed by coppicing (where trees are cut down to ground level) and pollarding in the plains (where trees are cut above the browse (or grazing) height of deer or cattle). In the case of coppicing, the regrowth has to be protected from browsing or grazing animals by fencing, ditches and banks. There were a number of uses for the cut wood, including firewood, fences, thatching spars, furniture and flood defences. The methods used remained unchanged for centuries and are described by Thomas Hardy in The Woodlanders. Some trees, rather than being coppiced, were left
