A disaster is a serious problem occurring over a short or long period of time that causes widespread human, material, economic or environmental loss which exceeds the ability of the affected community or society to cope using its own resources.
In the aerospace context, a disaster refers to an event or situation that causes significant harm, destruction or damage to people, property, and/or the environment. It can be caused by human error or natural phenomena and can have a major impact on aerospace operations, infrastructure, and safety.
Examples of disasters in the aerospace context include:
- Aircraft crashes, which can result in loss of life and damage to aircraft and infrastructure.
- Severe weather events, such as hurricanes, tornadoes, and thunderstorms, which can damage aircraft, runways, and other airport infrastructure, disrupt air travel, and cause significant harm to people and communities.
- Natural disasters, such as earthquakes, volcanic eruptions, and tsunamis, which can damage or destroy airports and other aerospace infrastructure, disrupt air travel and cause widespread harm to people and communities.
- Technological or human-made disasters, such as a cyber-attacks or terrorist attacks, which can damage or destroy aerospace infrastructure and disrupt air travel.
Aerospace organizations have plans and procedures in place to respond and recover from disasters, these plans are designed to minimize the impact of a disaster and to ensure the safety and well-being of those affected by it. In the event of a disaster, aerospace organizations may work closely with other organizations, such as emergency services, to respond and recover from the event.
There have been several major disasters in the aerospace context throughout history. Some examples include:
-
Tenerife airport disaster, 1977: Two Boeing 747 aircraft collided on the runway at Tenerife's Los Rodeos Airport (now Tenerife North Airport), resulting in 583 fatalities, making it the deadliest aviation accident in history.
-
Japan Airlines Flight 123, 1985: A Boeing 747SR suffered a mechanical failure caused by improper maintenance and crashed into a mountain in Japan, killing 520 people.
-
Space Shuttle Challenger disaster, 1986: The Space Shuttle Challenger broke apart 73 seconds into its flight, killing all seven crew members on board. The accident was caused by a failure in the O-ring seals on one of the solid rocket boosters.
-
Air France Flight 447, 2009: An Airbus A330 crashed into the Atlantic Ocean, killing all 228 people on board. The accident was caused by a combination of factors, including a failure in the aircraft's speed sensors and a lack of proper training and procedures for dealing with the resulting stall.
-
Malaysia Airlines Flight MH370, 2014: A Boeing 777 went missing on a flight from Kuala Lumpur, Malaysia, to Beijing, China, with 239 people on board. The wreckage has not been found yet, but it is believed to have crashed into the Indian Ocean, making it one of the most mysterious aviation accidents in history.
-
Germanwings Flight 9525, 2015: A co-pilot deliberately crashed an Airbus A320 into the French Alps, killing all 150 people on board.
These are just a few examples of major aerospace disasters. Each of these accidents had a significant impact on the aviation industry and the families of those affected. It led to changes in regulations, procedures, and technology to make the aerospace industry safer.
