Tourist helicopter hit flock of birds before crashing into the Hudson River last April, NTSB says

NTSB Investigation Reveals Helicopter Collision with Geese Before Hudson River Crash

Crash Details and Timeline

Tourist helicopter hit flock of birds – The National Transportation Safety Board has published a comprehensive set of investigative documents concerning a sightseeing helicopter that met its fate in the Hudson River near New York City during the previous year. According to these reports, which were made public on Thursday, the aircraft struck a group of geese prior to breaking apart and plunging into the water below. The tragedy claimed the lives of five passengers—a family consisting of three children and their parents—along with the pilot who was at the controls.

The Bell 206L-4 model helicopter, belonging to New York Helicopters, departed from lower Manhattan on April 11, 2025. Passengers enjoyed views of the Statue of Liberty as the aircraft circled overhead before proceeding northward along the Hudson River. Upon completing its route, the helicopter turned back toward the south. While positioned close to the New Jersey coast, the aircraft suddenly disintegrated in midair, tumbling and spinning before entering the river.

Avian Identification and Debris Analysis

Specialists at the Smithsonian Institution’s feather identification laboratory conducted thorough examinations to determine which birds were involved. Their findings revealed that a mixed-species flock containing both Brant and Canada Geese collided with the helicopter’s rotor blades and rear section. Additionally, the laboratory discovered that a Great Blackbacked Gull had been struck by debris ejected from the tail section with sufficient force to severely damage the bird and cause its wing to detach. This wing fragment eventually landed on a rooftop alongside other pieces of the helicopter.

“Bird remains were identified using whole/fragmentary feather comparisons with preserved bird specimens, microscopic examinations of diagnostic characters, and DNA analyses,” according to a report by the feather lab and included in the docket.

While the Smithsonian is widely recognized for its public museums located in Washington, the institution also provides valuable assistance to aviation investigators by identifying bird remains—commonly referred to as snarge—following aircraft collisions.

Witness Accounts of the Incident

Several individuals who observed the event provided detailed descriptions to investigators. One resident of a nearby apartment complex recalled watching the helicopter descend rapidly, describing it as falling “like a brick” into the water. This witness noted seeing hundreds of birds in the vicinity but could not remember their exact altitude at the time.

Another observer was jogging along the Hudson Riverbank when approximately twenty large, heavy birds suddenly took flight directly ahead of her, heading toward the river. Roughly two minutes afterward, she heard a loud bang overhead. However, she did not observe any birds in the immediate vicinity of the helicopter as it broke apart in the sky.

Victims and Ongoing Investigation

The passengers who perished included three children and their parents, both of whom were employed by Siemens, a German multinational technology conglomerate. The pilot was also among those killed in the accident. According to NTSB records, the helicopter’s most recent major inspection occurred on March 1, and it had already completed seven tour flights on the day of the crash.

The NTSB’s investigation encompasses more than 2,000 pages of materials, though these documents do not yet specify a probable cause for the disaster. Officials indicated to CNN that the final report, which will include this determination, is likely to be released by the end of the year.

Broader Context and Statistics

Wildlife strikes represent a significant concern for aviation safety. The Federal Aviation Administration’s wildlife strike database recorded over 24,000 incidents of aircraft colliding with animals last year. More than 1,000 of these occurrences took place in either New York or New Jersey.

The Hudson River holds historical significance in aviation history as the location of the “Miracle on the Hudson.” In 2009, Captain Chesley “Sully” Sullenberger successfully landed US Airways flight 1549 in the river after Canadian Geese disabled both engines of his Airbus A320 shortly after departure from LaGuardia Airport.

The FAA has noted that bird strike reports have increased in recent years due to several factors, including growing wildlife populations, higher flight volumes, faster and quieter aircraft, and improved reporting methods. Mitigation strategies currently being implemented involve habitat management, wildlife detection and prediction systems, and efforts to deter animals from flight paths.
