Risk Reality

Are Helicopters More Dangerous Than Planes?

Headlines Over the River

On April 10, 2025, a Bell 206L-4 tour helicopter took off from a heliport in lower Manhattan, flew up the Hudson to the George Washington Bridge, turned back south, and about 17 minutes into the flight came apart in the air. The pilot and a family of five visiting from Spain, three of them children, were killed. The NTSB’s preliminary report found the helicopter had broken into three main pieces (fuselage, main rotor and tail boom) before it hit the water. Factual records released in July 2026 found goose remains on the main rotor blades, pointing to a bird strike, though the NTSB has not yet issued a probable cause.

Ten weeks earlier, an Army Black Hawk had collided with an American Eagle regional jet over the Potomac, killing 67 people in the deadliest US air crash since 2001. Between the two, 2025 left a lot of people with the impression that helicopters fall out of the sky with some regularity.

The national numbers point the other way. The US Helicopter Safety Team, an FAA and industry group that tracks every civil rotorcraft accident, counted 30 deaths in calendar 2024, the fewest in 25 years. Fiscal 2025, which included the Hudson crash, came in at 41. The Black Hawk does not appear in either figure, because military aircraft sit outside civil accident statistics. Set against roughly 41,000 road deaths a year, helicopters look like a rounding error.

A Small Toll From a Small Amount of Flying

Forty deaths is a small number because helicopters fly very little. The entire US civil fleet logs about 3 million flight hours a year. Compare helicopters with anything else and you have to divide by the hours. Once you do, the picture flips.

Over 2020 to 2024, US civil helicopters averaged 0.63 fatal accidents per 100,000 flight hours, or one for every 160,000 hours in the air. Each fatal accident kills about two people. Spread across the people on board, an hour in a helicopter carries a fatality risk of roughly 1 in 227,000.

The flying article worked out the airliner equivalent. A commercial flight carries about a one-in-ten-million fatality risk per boarding, and the average flight lasts two to three hours, so an hour in an airliner seat comes out near 1 in 25 million. The helicopter hour is about a hundred times riskier. The same analysis put driving at about ten times the airline rate per hour, which leaves the helicopter roughly ten times riskier than the car.

So the answer to the headline question is yes, by a wide margin. Helicopters lack the things that make airline flying so safe. Most civil helicopters are single-engine machines with one pilot, flying low under visual rules, often into unprepared landing sites, with no second crew member to catch a mistake. An airliner has two engines, two pilots, instrument approaches, and radar separation from takeoff to touchdown.

It Depends Who Is Flying

“Helicopter” covers a dozen different businesses, and they do not share a risk profile. In a 2020 white paper, the Flight Safety Foundation broke down eleven years of USHST data (2009 to 2019, 34 million flight hours, 233 fatal accidents) by type of operation. Against an overall rate of 0.69 fatal accidents per 100,000 hours, it found:

Private flying ran at more than eight times the industry average and about seventeen times the rate for tours. The Foundation cautioned that the personal category probably includes some flights that were commercial in all but paperwork. Even so, the gap is large. A private owner with no company training or maintenance program behind them is doing something very different from a tour operator flying the same route many times a day.

Medical helicopters show how far a sector can move. Helicopter air ambulances had a bad reputation in the 2000s. In 2009, after a sharp rise in fatal crashes, the FAA put their fatal accident rate at 1.18 per 100,000 hours. Operators now report to the FAA every year under federal law, and the most recent reports show 0.39 fatal accidents per 100,000 hours in 2024 and 0.57 in 2025, across more than half a million flight hours a year.

Then there is the tour paradox. Sightseeing flights have the lowest rate per hour of the categories the Foundation singled out, yet they produce a disproportionate share of the headlines, for two reasons. They fly over famous places with cameras pointed at them, and they carry as many as seven passengers, so a single crash becomes a mass-casualty event. A 2009 study of Hawaii air tours by Haaland, Shanahan and Baker found 59 crashes between 1981 and 2008, of which 16 were fatal and killed 46 tourists and 9 pilots. After a 1994 federal rule aimed specifically at Hawaii tours, the crash rate fell 47%, from 3.4 to 1.8 per 100,000 flight hours. Low rate per hour, high toll per crash, maximum coverage.

The Chain of Probabilities

The calculator uses two fixed steps and one slider. The slider is the number of hours per year you spend aboard a helicopter.

The first fixed step is the chance that any given flight hour ends in a fatal accident. The calculator uses the USHST five-year average for 2020 to 2024 of 0.63 per 100,000 hours. Single years swing around it, from 0.79 in 2020 to a 25-year low of 0.44 in 2024, with fiscal 2025 back up at 0.66. The average covers every kind of civil flying, from crop spraying to news helicopters, so it understates the risk of private flying and overstates the risk of a tour.

The second is the chance that you personally die, given that your helicopter has a fatal accident. USHST counts give about two deaths per fatal accident (30 deaths in 13 fatal accidents in 2024, 41 in 20 in fiscal 2025). The light helicopters involved usually carry two or three people, so the calculator assumes about 70% of those on board die. This step is a site estimate, since no agency publishes a survival rate for helicopter occupants.

Multiplied together, an hour aboard comes to about 1 in 227,000. As a sanity check, take the fleet’s roughly 3 million flight hours a year with an average of 2.75 people on board. That is about 8 million person-hours, the equivalent of 8 million people each taking a single one-hour flight. At 1 in 227,000 per hour, that produces around 36 deaths a year, against 30 in 2024 and 41 in fiscal 2025.

Your Actual Risk

At the default of one hour a year, a sightseeing flight on holiday, the annual risk is about 1 in 227,000. That is seventy times the risk of being killed by lightning and a small fraction of the year’s driving risk. One hour in the helicopter carries about as much risk as 40 airline flights.

Ten hours a year, a commuter who takes a helicopter to the airport now and then, raises it to about 1 in 23,000. At 500 hours, a plausible year for a full-time professional crew member, it reaches roughly 1 in 450, almost eighteen times the annual risk of dying in a car crash.

The calculator uses the industry average, so adjust for who is at the controls. Private flying at the Foundation’s 5.94 rate makes each hour about nine times riskier than the calculator’s figure, or around 1 in 24,000 per hour. A tour hour runs at about half the default. For an air ambulance crew, the recent FAA figures put the rate slightly below the default.

The crashes that make the news are not the typical ones. In the first ten months of fiscal 2025, 6 of the 17 fatal US helicopter accidents were personal or private flights, more than any other category. Few of them made national news.

Methodology & sources

This calculator multiplies chained probabilities:

  1. Hours aboard
  2. Fatal accident: 0.0000063 — USHST five-year average (CY2020-2024): 0.63 fatal accidents per 100,000 flight hours, all US civil helicopters. CY2020 was 0.79, CY2024 a 25-year low of 0.44, FY2025 0.66
  3. You are among the dead: 0.7 — Site estimate. USHST data show about 2 deaths per fatal accident (30 deaths in 13 fatal accidents in CY2024, 41 in 20 in FY2025). Assuming an average of 2.5 to 3 people aboard the light helicopters involved gives roughly 70%. Cross-check: default exposure gives 1 in 227,000 per hour aboard; ~3 million flight hours a year with ~2.75 people aboard is ~8 million person-hours, which produces ~36 deaths a year against 30 (CY2024) and 41 (FY2025) actual.
