Transport-related news last week included a report about a Singapore Airlines B777 jet flying to London from Singapore that had to make an emergency landing in Bangkok due to extreme turbulence experienced. Many people were seriously injured when the plane suddenly ascended (“tilted up” as some news reports state) and then abruptly descended, resulting in people being tossed up and hitting the compartments above their seats. Obviously, these passengers were not wearing their seatbelts at the time. Otherwise, they would have been restrained to their seats. It is likely that the turbulence was not anticipated by the pilot as they usually advise passengers to put on their seat belts if turbulence was expected at any time during a flight.

The incident raises concerns about extreme and sudden turbulence occurring during flights. I guess this may happen anytime and aircraft instruments may not be able to tell the crew about an impending incident like this. Will such an incident have a significant impact on air travel? Perhaps not if these incidents remain rare. There should be records and monitoring of factors or elements leading to such incidents in order to establish the likelihood of these happening. Incident records will also show if there is an increasing frequency as well as the number of people killed and injured. Such information would be vital as more people use aviation for travel and there are more aircraft activity around the world.

As a precaution, it is good practice not to remove your seatbelt while seated in flight. If it’s tight, then loosen it. At least you have some restraint in case of incidents where the aircraft encounters sudden turbulence.
