Around 5:30 p.m. on May 16, 1977, a normal Monday evening in New York City turned into a deadly disaster.
David Tumi, a 39-year-old lawyer, was waiting outside the Pan-Am Building in Midtown Manhattan. He was preparing to take a helicopter to the airport. The service was expensive, but it was designed for passengers who wanted to avoid the city’s traffic and reach the airport quickly.
Tumi was already worried about being late for his flight. He had no idea that the helicopter waiting above him was about to become the center of a tragedy that would change helicopter operations in New York City.
At the same time, Anne Barnett was standing at a nearby bus stop. She was waiting for a bus home to the Bronx.
Within minutes, both of their ordinary commutes would become part of one of New York’s most shocking aviation accidents.
David Tumi Was Waiting for a Helicopter to the Airport
David Tumi had arrived at the Pan-Am Building during the evening rush hour. He was in a hurry because he had a flight to catch.
The helicopter service operating from the building was intended to save passengers time. Instead of traveling through Manhattan traffic by road or taking public transportation, passengers could pay more for a direct helicopter trip to the airport.
For people who could afford it, the service was an attractive option.
The helicopter had arrived at the rooftop landing area, and passengers who had been on board were getting off. Tumi and the other waiting passengers prepared to board.
As he waited, Tumi briefly looked up at the sky.
It would be one of his final moments outside.
The Helicopter Was Still Running
The helicopter was not shut down while passengers changed.
The practice saved time. The operator wanted the aircraft ready to leave as soon as passengers had boarded.
But keeping a helicopter running while people were getting on and off also meant that its machinery was under continuous stress.
On that afternoon, something went badly wrong.
A supporting component associated with the helicopter’s landing gear failed while the aircraft was still operating.
The helicopter suddenly tipped onto its side.
Its rotor blades were still spinning at high speed.
The Rotor Blades Broke Apart
When the helicopter tipped over, its spinning rotor struck the rooftop.
The impact caused the blades to break apart.
Pieces of the rotor began moving across the rooftop at tremendous speed.
People waiting to board had almost no time to react.
Tumi and several other people were struck by the out-of-control rotor blades. Four people on the rooftop, including Tumi, were killed.
What had started as a routine airport transfer had become a deadly accident within seconds.
But the danger did not stop at the rooftop.
Metal and Glass Fell Onto the Streets
Some of the broken rotor pieces went over the edge of the building.
The Pan-Am Building was a 59-story skyscraper in the heart of Manhattan. As the debris fell, it struck windows and other parts of the building.
Glass shattered from the impact.
Metal fragments and pieces of the helicopter continued toward the crowded streets below.
People on the ground had little warning.
Anne Barnett Was Caught in the Debris
Nearby, Anne Barnett was waiting at a bus stop.
She was surrounded by the normal rush-hour crowd. People were leaving work, heading home and moving through the busy streets.
Then she heard a series of strange and frightening noises.
There was a loud boom, followed by sharp cracking sounds and the roar of breaking glass.
People began running.
Barnett instinctively raised her arms to protect her head.
But the falling debris reached the street almost immediately.
She was struck and killed by a piece of the helicopter.
Barnett became the fifth fatality in the accident.
Why the Accident Was So Dangerous
The tragedy involved several factors that made the accident especially destructive.
The Helicopter Was Operating at Full Power
The aircraft was still running while passengers were boarding.
That allowed the operator to save time, but it also meant the rotor system was active when the helicopter tipped over.
The Aircraft Was on a Skyscraper
The accident happened on the roof of a 59-story building.
When the rotor blades broke apart, the height turned the accident into a danger for people far below.
Manhattan Was Crowded
The accident occurred during the evening rush hour.
The streets around the building were filled with pedestrians and vehicles. There were many people in the area who had no connection to the helicopter but were exposed to falling debris.
The Pan-Am Building Helipad Was Closed
The accident had immediate consequences.
The rooftop helicopter operation at the Pan-Am Building was permanently closed after the disaster.
The tragedy also raised serious questions about the safety of commercial helicopter operations from skyscraper rooftops.
A system designed to save passengers a few minutes had created a serious risk in one of the world’s busiest cities.
New York City Changed Its Helicopter Rules
The accident became an important turning point for helicopter operations in New York City.
Commercial helicopter landings on skyscrapers were ultimately banned in the city as a result of the tragedy.
The decision reflected a simple problem: an accident on a rooftop hundreds of feet above the street could affect far more people than those inside the aircraft.
The Pan-Am Building accident showed how a mechanical failure on a rooftop could quickly become a disaster on the ground.
A Routine Commute Became a Historic Tragedy
David Tumi was trying to save time.
Anne Barnett was simply trying to get home.
Neither person had any reason to expect that a helicopter accident high above Manhattan would change the course of their evening.
The accident killed five people and ended commercial helicopter operations from the Pan-Am Building’s rooftop. More broadly, it demonstrated the risks of operating aircraft from skyscrapers surrounded by crowded city streets.
For Tumi, Barnett and the other victims, what began as an ordinary Monday in New York ended in tragedy.
And for the city, the accident became a lasting reminder that saving a few minutes of travel could carry a much greater cost when aviation and densely populated skyscrapers came together.
