Alcock and Brown, the Vickers Vimy, and the Sixteen Hours of Ice and Fog That Made the First Nonstop Transatlantic Flight

On June 14, 1919, John Alcock and Arthur Whitten Brown lifted a heavily loaded Vickers Vimy biplane off a rutted Newfoundland meadow and flew nonstop to Ireland, covering 1,890 miles in 16 hours and 28 minutes. No one had done it before. No one knew with certainty it could be done. The achievement settled both questions at once.

What Was at Stake: The Daily Mail Prize

In 1913, Lord Northcliffe of the Daily Mail put up £10,000 sterling - an enormous sum - for the first aviator to cross the Atlantic in a single continuous flight. The prize sat unclaimed for six years, mostly because a world war intervened.

That war reshaped the landscape in ways no one had anticipated. Aircraft technology advanced by a decade under the pressure of combat. By 1918, machines that could carry real weight across real distances existed in numbers. When the Armistice came in November 1918, the prize was still on the table, and a small army of aviators descended on Newfoundland the following spring.

Who Were Alcock and Brown?

John Alcock came from Manchester. He had learned to fly before the war, fought in the Dardanelles campaign, been shot down over the sea off Turkey, and spent two years as a prisoner of war. He was 36 years old in 1919. Those who flew with him described a natural authority over heavy aircraft - the kind of feel that cannot be taught.

Arthur Whitten Brown was an engineer before he was an airman. Born in Glasgow to American parents and raised in Manchester, he flew observation aircraft over the Western Front, was shot down, wounded in one leg, and taken prisoner in Germany. In the camp, with nothing to do, he studied celestial navigation. By the time the war ended, he could work a sextant as well as any sailor.

Vickers selected both men for the Atlantic attempt and provided the aircraft.

The Vickers Vimy: A Bomber Repurposed for an Ocean

The Vimy had been designed as a long-range bomber to raid Berlin. The war ended before it could fulfill that role. For the Atlantic attempt, the bomb bays and racks were stripped out and replaced with fuel tanks holding 865 gallons of gasoline. At the moment of takeoff, the aircraft weighed over 12,000 pounds - most of it fuel.

The engines were two Rolls-Royce Eagle VIIIs, each producing around 360 horsepower. Wingspan was 68 feet. The cockpit was open to the sky, unheated. Instrumentation was minimal even by 1919 standards: an airspeed indicator, a compass, an altimeter, a basic turn-and-slip indicator, and a bubble sextant for Brown’s navigation. No radio navigation. No weather information beyond what they could see.

The Competition and the Starting Field

Alcock and Brown were not alone that spring. Five or six teams had converged on Newfoundland chasing the same prize. The harbor town of St. John’s was crowded with aviators, mechanics, and journalists.

Harry Hawker and Kenneth Mackenzie-Grieve had already attempted it, departing on May 18 in a Sopwith Atlantic. Their engine overheated mid-ocean. They ditched. A Danish freighter with no radio pulled them from the sea, and for more than a week the world assumed they were dead. When their ship made port in Scotland, they were treated as heroes regardless - because by then, even the attempt meant something.

Frederick Raynham crashed on his takeoff run.

Alcock and Brown assembled their Vimy at Lester’s Field outside St. John’s and waited for weather. By June 14, the weather maps offered a window that was narrow and far from clean. Cloud covered most of the North Atlantic. Winds aloft were uncertain. Alcock decided it was enough.

The Takeoff

The Vimy rolled the length of the uphill field, shaking under the weight of all that fuel, and lifted free just before a stone wall at the field’s boundary. Brown wrote afterward that he was not certain they were actually flying until the trees dropped away beneath them.

They turned east. The Rolls-Royce engines settled into their deep, rhythmic thunder.

The First Hours: Workable, Then Not

For the first few hours, sky gaps appeared and Brown was able to get star shots, calling out heading corrections. They ate sandwiches, drank coffee from thermos flasks, and held approximately 110 mph indicated airspeed. The engines were steady.

Then the Atlantic closed in.

What followed was not a classic storm system but dense Atlantic fog - so total that Alcock had no visual reference at all. Without a visible horizon and with instruments far removed from a modern attitude indicator, spatial disorientation was not a risk. It was a certainty.

The Vimy entered a spiral dive.

Alcock felt it begin and could not stop it. The aircraft banked harder, the nose dropped, airspeed built, and the altimeter unwound. Somewhere below them in the dark was the North Atlantic.

They broke out of the overcast at fifty feet above the waves.

Brown saw the whitecaps close enough to make them out clearly. Alcock hauled back on the controls and leveled the wings on instinct, and they staggered back upward with the engines at full power and the entire airframe shaking from the stress of the recovery. The margin between that moment and the ocean floor was measured in feet and fractions of a second.

Brown Climbs Out onto the Wing

As altitude increased and temperature dropped, ice began forming on the nacelles, the leading edges, and critically, on the air intake scoops for the Rolls-Royce engines. Ice those scoops over and the engines begin to starve of air.

Brown solved this problem the only way available.

Six times during the crossing, Arthur Whitten Brown crawled out of the open cockpit, made his way along the lower wing structure toward the engine nacelles, and chipped ice off the intake scoops with a pocketknife. No effective safety harness. No heated suit. Just a man in a leather flying coat and goggles, hanging on by grip alone, hacking at ice in the dark and cold, then crawling back to his seat.

Each time Brown went out, Alcock held the aircraft as steady as possible without looking back. He kept his hands light on the controls and waited to feel Brown’s weight shift back into the seat beside him.

Landfall: Ireland

By the early morning hours of June 15, both men were exhausted and partially frostbitten. Then the Irish coast appeared.

Brown spotted a radio mast array near Clifden, in Connemara, on the west coast of Ireland. Beyond the masts was a wide stretch of what appeared to be smooth green grass.

It was Derrygimlagh Bog.

The wheels hit, sank immediately, and the aircraft pitched forward onto its nose. The undercarriage collapsed. The Vimy dug in and stopped. Both men climbed out, uninjured, into the soft Irish morning.

Local people ran across the bog toward them. Some thought the men might be German spies.

The Aftermath: Knighthood and Loss

Winston Churchill, then Secretary of State for War, ensured the prize money was delivered without delay. Within the week, both men were at Windsor Castle. King George V knighted them on the spot: Sir John Alcock and Sir Arthur Whitten Brown.

Six months later, in December 1919, Alcock was ferrying a new Vickers amphibian aircraft to an airshow in Rouen, France. The weather over Normandy was poor. He flew into fog. The aircraft came down in a field near the city. John Alcock died of his injuries two days later. He was 36 years old.

Brown was devastated. He never flew again.

He lived for another 39 years, quietly, in Wales. His son Raymond was killed flying in the Second World War. Brown accepted honors when asked and gave occasional talks, but carried the Atlantic crossing as a weight rather than a trophy. After Alcock died, that weight never fully lifted.

Why This Matters for Pilots

The navigation problem Alcock and Brown solved with almost nothing is worth sitting with. No electronic nav, no radio beacons - just a compass, a sextant, Brown’s mathematical skill, and a sky that was mostly overcast anyway. They navigated by dead reckoning across nearly 1,900 miles of open ocean, reached within miles of their intended landfall, and did it at night through cloud and icing conditions that nearly killed them twice.

Brown was holding a mental model of the sky and working backward from numbers until he could point east and say: Ireland is that way.

He was right.

The Vickers Vimy they flew is preserved today in the Science Museum in London, hanging in the main hall. The nose is still crumpled from the bog landing.

• The aircraft was a Vickers Vimy biplane powered by two Rolls-Royce Eagle VIII engines, with an open cockpit and no heating or radio navigation.
• Arthur Whitten Brown climbed out onto the wing six times mid-flight to chip ice off the engine intake scoops with a pocketknife.
• Both men were knighted by King George V within days of landing; Alcock was killed in a crash just six months later.
• The flight demonstrated that dead reckoning navigation - disciplined, math-based, without electronic aids - could guide an aircraft across an ocean, a foundation principle that every instrument-rated pilot still learns today.
