how many locks in the caen hill flight
Caen Hill Locks The 29 locks have a rise of 237 feet in 2 miles (72 m in 3.2 km) or a 1 in 44 gradient. The locks come in three groups. The lower seven locks, Foxhangers Wharf Lock to Foxhangers Bridge Lock, are spread over ¾ of a mile (1.2 km). The next sixteen locks form a steep flight in a straight line up the hillside and are designated as a scheduled monument.[2] Because of the steepness of the terrain, the pounds between these locks are very short. As a result, 15 locks have unusually large sideways-extended pounds, to store the water needed to operate them. A final six locks take the canal into Devizes.[3]

It crashed into a field in Somerset County, Pennsylvania, during an attempt by the passengers and crew to regain control. All 44 people aboard were killed, including the four hijackers, but no one on the ground was injured. The aircraft involved, a Boeing 757â€“222, was flying United Airlines' daily scheduled morning flight from Newark International Airport in New Jersey to San Francisco International Airport in California.
