Landmark Crash Investigations Timeline¶
About This MicroSim¶
Many of aviation's safety advances were paid for by a single tragic accident. This interactive timeline collects eight landmark crash investigations whose findings reshaped how aircraft are built, inspected, and flown.
Each milestone is color-coded by the kind of forensic lesson it taught — structural failure, human factors, explosion and reconstruction, or flight recorders. Hover a milestone for a one-line summary, or click it to read what the investigation found and which technique it advanced.
How to Use It¶
- Read the milestones left to right, from the 1954 Comet to the 2009 Air France and Colgan investigations.
- Hover any milestone for a quick summary.
- Click a milestone to open the detail panel with the key finding and the forensic technique or safety reform it produced.
- Use the theme buttons to filter by lesson type (for example, show only the Structural & metallurgical cases).
- Use ◀ ▶ to pan, + − to zoom, and Fit All to see every milestone.
What You Can Learn¶
- Identify eight landmark crash investigations and when each occurred.
- Match each investigation to the forensic technique or safety reform it advanced — from rounded windows to fuel-tank inerting to 90-day locator beacons.
- See how the same technique (metallurgical fatigue analysis) recurs across decades and different accidents.

Lesson Plan¶
Audience: High-school forensic science (grades 9–12) Time: 10–15 minutes Bloom level: Remember (L1) — identify landmark investigations.
Routine. Have students click every milestone and fill in a three-column table: year, crash, forensic advance. Then filter by theme and ask which lesson recurs most often.
Guided questions:
- Which two milestones taught lessons about metal fatigue? What changed in aircraft design as a result?
- Which milestone led to Crew Resource Management training?
- Why did Air France 447 change the rules for underwater locator beacons?
- Two different crashes happened in 1988. What different forensic lesson did each one teach?
Extension. Pair this timeline with the Debris Field Pattern Explorer and the chapter's metallurgy section: for Pan Am 103 and TWA 800, describe how the debris field and the reconstructed wreckage together pointed to the cause.

Specification¶
This MicroSim was generated from a specification in Chapter 19: Aviation Crash Forensics and Aircraft Accident Investigation.
Design note: the milestones are colored by forensic-lesson theme rather than by date, so learners can filter to see how one kind of technique (for example, metallurgical fatigue analysis) recurs across decades.
