It is believed that the origins of National Checklist Day can be traced back to this time. In fact, the day is celebrated on the anniversary of the crash of a Boeing Model 299, which took place on October 30, 1935. It was after this airplane crash that the pre-flight checklist was introduced and adopted as a permanent, mandatory tool for pilots.
Today, the checklist is not only used for aviation safety, but it has also been implemented in a variety of other industries and workplaces. National Checklist Day was established in the 1950s and has been part of many different people’s lives each year ever since that time.
