Recently, two tragic accidents involving the Boeing 737 Max 8 aircraft have raised questions about airplane safety. While flying is generally considered very safe, these incidents make us wonder why some planes crash and if there are safer ways to fly.
Commercial flights are incredibly safe. For example, in 2017, there was only one fatal accident for every 16 million flights. However, small private planes have crash rates similar to cars. Most plane accidents happen due to pilot errors or when pilots accidentally fly into the ground or obstacles. This is more common with amateur pilots who have less training and face fewer regulations than commercial pilots.
From 2010 to 2018, there were 1,182 plane accidents. These can be grouped into four main causes: human error, weather, mechanical failure, and sabotage. Human error is the most common cause, with mistakes often related to skills and decision-making.
Skill-based errors include not conducting proper visual checks, accidentally flipping switches, and not following checklists. Checklists are vital for pilots and crew to ensure all necessary tasks are completed before takeoff, reducing risks significantly. For instance, a 2014 crash that killed seven people could have been avoided if the pre-flight checklist had been followed, and a piece of equipment called the gust lock had been released before takeoff.
Decision-making errors involve making poor choices. In the same crash, pilots tried to fix the gust lock issue during the flight instead of aborting takeoff. Ensuring pilots get enough rest can help reduce human error, as fatigue is a common problem that increases accident risks.
Weather is a factor in about a quarter of American plane accidents, with dangerous conditions including rain, low clouds, and fog, which reduce visibility. December and January are the riskiest months for flying. A famous accident in 1977 involved two Boeing 747s colliding on a foggy runway, resulting in 583 deaths.
Mechanical issues cause 23% of fatal accidents, with engine failure being the most common. Large jets are less likely to have these problems compared to smaller planes. For example, an Air France crash was caused by a frozen pitot tube, which measures airspeed. Incorrect speed readings can lead to dangerous situations like stalling or structural failure.
Sabotage is the least common cause of crashes, responsible for 7% of fatalities, including events like the September 11 attacks.
If you ever find yourself in a crash, sitting at the back of the plane might increase your chances of survival. A study found that passengers in the back had a 69% chance of survival, compared to 49% for those in the front. A 2012 test with crash test dummies in a Boeing 727 supported this finding.
The black box, a device that records flight data and cockpit audio, is located at the back of the plane. This data helps understand accidents, like the Ethiopian Airlines flight 302 and the Indonesian Lion Air flight 610, both of which had sharp altitude changes.
While these accidents are tragic, it’s important to remember that air travel is still one of the safest ways to travel.

Research the safety measures implemented in modern aviation, focusing on how they address the main causes of plane crashes. Prepare a short presentation to share your findings with the class, highlighting any new technologies or protocols that have been introduced to improve safety.
Analyze the Boeing 737 Max 8 incidents by reviewing available reports and articles. Identify the key factors that contributed to these accidents and discuss how they relate to the main causes of plane crashes mentioned in the article. Write a brief report summarizing your analysis.
Participate in a flight simulation activity where you take on the role of a pilot. Make decisions based on various scenarios, such as adverse weather conditions or mechanical failures. Reflect on how these decisions could impact flight safety and discuss the importance of training and checklists.
Conduct an experiment to understand how weather conditions affect flight safety. Use a model airplane and simulate different weather scenarios, such as fog or rain, to observe their impact on visibility and control. Record your observations and discuss how pilots can mitigate these risks.
Engage in a classroom debate on whether human error or mechanical failure poses a greater risk to aviation safety. Use evidence from the article and additional research to support your arguments. Conclude with a discussion on how both factors can be addressed to enhance safety.

Two recent flights involving the Boeing 737 Max 8 aircraft experienced altitude fluctuations, resulting in tragic accidents that claimed the lives of everyone on board. While flying is often considered extremely safe, questions arise about why some planes crash and whether there are safer seats or times of day to fly.
Commercial flights are indeed very safe. For instance, in 2017, there was one fatal accident for every 16 million flights. However, small private planes have crash rates comparable to those of cars. Most accidents occur due to pilot error or controlled flight into terrain, where the pilot fails to see the ground or obstacles until it’s too late. Generally, amateur pilots have significantly less training and face looser regulations than commercial pilots.
According to the Bureau of Aircraft Accidents archives, there were 1,182 accidents from 2010 to 2018. These accidents can be categorized into four main causes: human error, weather, mechanical failure, and sabotage. Human error is the leading cause of crashes, with data from 1,020 commercial flight accidents indicating that these errors are primarily skill-based and decision-making errors.
Skill-based errors include failing to conduct proper visual scans, mistakenly toggling switches, and not following checklists. A pre-flight checklist is crucial for pilots and crew to perform necessary tasks before takeoff, significantly reducing risk. For example, a 2014 crash that resulted in seven fatalities could have been avoided if the pre-flight checklist had been completed and a piece of equipment, the gust lock, had been released before takeoff.
Decision-making errors involve conscious choices that lead to poor outcomes. In the aforementioned crash, the pilots attempted to disengage the gust locks after realizing the issue, rather than aborting the flight. Human error can be mitigated by ensuring adequate rest; studies have shown that a significant percentage of pilots experience fatigue, and longer duty times correlate with a higher probability of accidents.
Weather-related factors contributed to a quarter of American plane accidents from 1982 to 2013, with the most dangerous conditions being precipitation, low cloud cover, and fog, all of which impair visibility. December and January are statistically the most hazardous months for travel. A notable incident occurred in 1977 when two Boeing 747s collided on the runway in thick fog, resulting in 583 fatalities.
Mechanical failures account for 23% of fatal accidents, with engine failure being the primary issue. However, large jet aircraft are less likely to experience these failures compared to smaller propeller planes. For instance, an Air France Airbus crash was attributed to a frozen pitot tube, which measures airspeed. Inaccurate speed readings can lead to dangerous situations, such as stalling or structural failure due to excessive speed.
Sabotage is the least common cause of crashes, accounting for 7% of fatalities, including incidents like the September 11 attacks.
If you find yourself in a crash, a 2007 analysis by Popular Mechanics revealed that passengers seated in the back of the plane had a 69% chance of survival, compared to 49% for those in the front. A 2012 test with a Boeing 727 filled with crash test dummies supported these findings, indicating that the front is not the safest place to sit.
The black box, a highly protected device that records flight data and cockpit audio, is located at the back of the plane. This data has been instrumental in understanding accidents, such as the Ethiopian Airlines flight 302 and the Indonesian Lion Air flight 610, both of which experienced sharp altitude fluctuations.
While these events are tragic, it’s essential to remember that air travel remains one of the safest modes of transportation. Thank you for watching.
