Part 3/8:
Just before takeoff, the pilots reported an abnormal temperature reading from the ram air temperature probe. This sensor is crucial for monitoring air temperature—essential for managing engine thrust and preventing engine damage during flight. Concerned about the malfunction, the crew decided to return to the gate for a thorough inspection, marking the first of several decisions that would tragically set the stage for disaster.
Ironically, it turned out that the reading had likely been erroneous due to a heating element in the probe malfunctioning while the aircraft was on the ground. This meant that the aircraft was, in actuality, fit for takeoff—an unfortunate misstep rooted in safety consciousness.
