Part 4/11:

Flight 301 took off shortly after 11:30 PM. As the crew relied on their instruments due to the night conditions, they checked airspeed indications, which are vital for the safe operation of the flight. Just before reaching takeoff speed, the captain's airspeed indicator failed, showing zero while the first officer's was functioning correctly. The captain made a critical decision: to proceed with takeoff, believing the first officer's indicator to be accurate.
