Document 2: Battle of Princeton: The Battle of Princeton was a battle of the American Revolutionary War, fought near Princeton, New Jersey on January 3, 1777. Lieutenant General Charles Cornwallis had left 1,400 British troops under the command of Lieutenant Colonel Charles Mawhood in Princeton. Following a surprise attack at Trenton early in the morning of December 26, 1776, General George Washington of the Continental Army decided to attack the British in New Jersey before entering winter quarters. On December 30, he crossed the Delaware River back into New Jersey. His troops followed on January 3, 1777. Washington advanced to Princeton by a back road, where he pushed back a smaller British force but had to retreat before Cornwallis arrived with reinforcements. The battles of Trenton and Princeton were a boost to the morale of the Continental troops, leading many recruits to join the Continental Army in the spring.
Document 3: Battle of Trenton: The Battle of Trenton was a small but pivotal battle during the American Revolutionary War which took place on the morning of December 26, 1776, in Trenton, New Jersey. After General George Washington's crossing of the Delaware River north of Trenton the previous night, Washington led the main body of the Continental Army against Hessian mercenaries garrisoned at Trenton. After a brief battle, almost two - thirds of the Hessian force was captured, with negligible losses to the Americans. The battle significantly boosted the Continental Army's flagging morale, and inspired re-enlistments.

Document 6: Bermuda: After several failed attempts, in 1930 the first aeroplane reached Bermuda. A Stinson Detroiter seaplane flying from New York, it had to land twice in the ocean: once because of darkness and again to refuel. Navigation and weather forecasting improved in 1933 when the Royal Air Force (then responsible for providing equipment and personnel for the Royal Navy's Fleet Air Arm) established a station at the Royal Naval Dockyard to repair (and supply replacement) float planes for the fleet. In 1936 Luft Hansa began to experiment with seaplane flights from Berlin via the Azores with continuation to New York City.
Document 7: Hydrogen: Hydrogen was liquefied for the first time by James Dewar in 1898 by using regenerative cooling and his invention, the vacuum flask. He produced solid hydrogen the next year. Deuterium was discovered in December 1931 by Harold Urey, and tritium was prepared in 1934 by Ernest Rutherford, Mark Oliphant, and Paul Harteck. Heavy water, which consists of deuterium in the place of regular hydrogen, was discovered by Urey's group in 1932. François Isaac de Rivaz built the first de Rivaz engine, an internal combustion engine powered by a mixture of hydrogen and oxygen in 1806. Edward Daniel Clarke invented the hydrogen gas blowpipe in 1819. The Döbereiner's lamp and limelight were invented in 1823.
Document 8: Hydrogen: In the same year the first hydrogen-cooled turbogenerator went into service with gaseous hydrogen as a coolant in the rotor and the stator in 1937 at Dayton, Ohio, by the Dayton Power & Light Co.; because of the thermal conductivity of hydrogen gas, this is the most common type in its field today.
Document 9: American Revolutionary War: British attempts to disarm the Massachusetts militia at Concord in April 1775 led to open combat. Militia forces then besieged Boston, forcing a British evacuation in March 1776, and Congress appointed George Washington to command the Continental Army. Concurrently, an American attempt to invade Quebec and raise rebellion against the British failed decisively. On July 2, 1776, the Continental Congress voted for independence, issuing its declaration on July 4. Sir William Howe launched a British counter-offensive, capturing New York City and leaving American morale at a low ebb. However, victories at Trenton and Princeton restored American confidence. In 1777, the British launched an invasion from Quebec under John Burgoyne, intending to isolate the New England Colonies. Instead of assisting this effort, Howe took his army on a separate campaign against Philadelphia, and Burgoyne was decisively defeated at Saratoga in October 1777.

Document 12: Hydrogen: The first non-stop transatlantic crossing was made by the British airship R34 in 1919. Regular passenger service resumed in the 1920s and the discovery of helium reserves in the United States promised increased safety, but the U.S. government refused to sell the gas for this purpose. Therefore, H2 was used in the Hindenburg airship, which was destroyed in a midair fire over New Jersey on 6 May 1937. The incident was broadcast live on radio and filmed. Ignition of leaking hydrogen is widely assumed to be the cause, but later investigations pointed to the ignition of the aluminized fabric coating by static electricity. But the damage to hydrogen's reputation as a lifting gas was already done.
Document 13: The Death of General Mercer at the Battle of Princeton, January 3, 1777: The Death of General Mercer at the Battle of Princeton, January 3, 1777 is the title of an oil painting by the American artist John Trumbull depicting the death of the American General Hugh Mercer at the Battle of Princeton on January 3, 1777 during the American Revolutionary War. The painting was Trumbull’s first depiction of an American victory. It is one of a series of historical paintings on the war, which also includes the "Declaration of Independence" and "The Capture of the Hessians at Trenton, December 26, 1776".

In July 2005, the flight was duplicated by American aviator and adventurer Steve Fossett in a replica Vickers Vimy aircraft, with St. John's International Airport substituting for Lester's Field (now an urban and residential part of the city).
