Key Takeaways:

Aviation checklists originated from the 1935 crash of the Boeing Model 299 prototype (XB-17), caused by a pilot forgetting a crucial step, leading to their adoption as a critical safety measure.
Checklists are indispensable tools for pilots, covering all flight phases, and are used in various formats, including electronic and "challenge and response" methods, to ensure tasks are completed logically and safely.
Pilot call signs are another tradition with military origins, often derived from an individual's last name, memorable incidents, or personal characteristics, and typically stick with the pilot.

The next time you pick up the checklist of your aircraft, remember this: It was created because of a horrible day in October 1935 when the Boeing Model 299 (XB-17), the prototype of the B-17, crashed during takeoff from Wright Field in Dayton, Ohio, in what was supposed to be a demonstration flight to earn a military contract.

The four-engine aircraft was the fastest and the most technologically advanced aircraft of the time. According to the official accident report, the aircraft lifted off, reached an altitude of approximately 300 feet, and then entered a stall. Two of the five crewmembers—including the pilot—were killed.
