The aircraft's pitch angle is critically important. When malfunctions occur, they can have fatal consequences. For example, Alaska Airlines Flight 261 entered a steep dive into the Pacific due to a defective horizontal stabilizer, killing everyone on board. A design flaw compounded by a severe storm also caused the crash of American Eagle Flight 4184. Investigators also suspect a technical defect in a crashed Boeing 737. However, when reconstructing these accidents, they initially find themselves in the dark.
