Natural Intruder

What is a Bird Strike in AviatBird strikes are a significant concern in aviation, referring to incidents where birds collide with aircraft during flight, takeoff, or landing. These events, while often overlooked by the general public, pose serious safety risks and financial implications for the aviation industry.

The Phenomenon of Bird Strikes

A bird strike occurs when a bird, or flock of birds, comes into contact with an aircraft, typically with the fuselage, wings, or engines. While modern aircraft are built to withstand small bird collisions, larger birds or flocks can cause catastrophic damage. Engines, in particular, are vulnerable, as ingesting birds can disrupt their operation, sometimes leading to engine failure.

The Most Famous Birdstrike Crushes

Bird strikes are a significant safety concern in aviation, and over the years, there have been several incidents where bird strikes have contributed to major accidents. Here are some of the most famous bird strike-related crashes:

US Airways Flight 1549 (2009) - The Miracle on the Hudson

One of the most famous bird strike incidents occurred on January 15, 2009, when US Airways Flight 1549 struck a flock of Canada geese shortly after takeoff from LaGuardia Airport in New York City. The strike caused both engines to fail, but Captain Chesley "Sully" Sullenberger and First Officer Jeffrey Skiles successfully made an emergency water landing in the Hudson River. Miraculously, all 155 people aboard survived. This event was widely publicized and became the subject of the 2016 film Sully.

British Airways Flight 5390 (1990)

Although the primary cause of this incident was not a bird strike, a bird strike occurred during the flight that contributed to the chain of events. The flight suffered a decompression, but a bird strike played a role in the failure of the plane’s forward windscreen. The incident famously resulted in the pilot being partially ejected from the aircraft but was saved due to the crew's quick thinking and emergency actions.

Delta Air Lines Flight 191 (1985)

While this crash was primarily caused by weather conditions, a bird strike also played a role in the aircraft's loss of control. On August 2, 1985, Delta Flight 191 crashed while attempting to land at Dallas/Fort Worth International Airport. Several bird strikes occurred during the approach, but the major contributing factor was a microburst thunderstorm. However, this event highlighted the potential dangers posed by bird strikes when combined with other hazardous conditions.

American Airlines Flight 1 (1995)

In 1995, an American Airlines flight departing from Los Angeles International Airport was struck by a bird during takeoff. The bird strike caused a large hole in one of the engines, and although the flight was able to return to the airport safely, the incident raised awareness about bird strike risks during high-speed takeoffs.

JetBlue Airways Flight 292 (2005)

While a bird strike didn’t directly cause this incident, it did involve a failure that could have been caused by one. On September 21, 2005, JetBlue Flight 292 experienced a malfunction with its nose landing gear after departing from Burbank, California. Although bird strikes were not the primary cause, the possibility of a bird strike being involved in the malfunction was speculated. The crew successfully landed the plane with no fatalities, but the incident highlighted the dangers of unanticipated mechanical failures.

These incidents underscore the importance of bird strike mitigation efforts, such as wildlife management around airports, bird radar systems, and aircraft design improvements to reduce the risks of bird-related accidents.

The Aftermath: Understanding Snarge

In aviation terminology, the remnants of a bird after a collision with an aircraft are referred to as snarge. While the word might sound unusual, snarge plays a crucial role in aviation safety. By analyzing these remains, aviation experts can determine the bird species involved in the strike. This information helps engineers design more resilient engines and aids in creating strategies to reduce the risk of bird strikes near airports.

The Risks Associated with Bird Strikes

The consequences of bird strikes vary depending on factors such as the size of the bird, the speed of the aircraft, and the location of the impact. Potential risks include:

Engine failure or damage

Cracked windshields

Structural damage to wings or fuselage

Emergency landings or aborted takeoffs

In extreme cases, bird strikes have resulted in fatal crashes, highlighting the importance of ongoing research and preventive measures.

Preventive Measures

Airports and aviation authorities employ several strategies to mitigate the risk of bird strikes:

Wildlife Management. Using trained falcons or noise devices to deter birds.

Airport Design. Reducing water sources and vegetation that attract birds.

Technology. Radar systems that detect bird activity in real time.

Engineering Resilience

Aircraft engines are subjected to rigorous testing to withstand bird strikes. For example, engines must endure simulated bird strikes using artificial bird models during certification. However, these tests have limitations, and engineers continuously refine engine designs based on real-world data.

Conclusion

Bird strikes remain a persistent challenge in aviation, but advancements in technology, wildlife management, and engineering continue to improve safety standards. Understanding incidents like these enhances aviation safety and contributes to preserving both human and avian lives.

Next time you're at an airport, take a moment to appreciate the measures to keep both aircraft and birds safe in the skies.
