Pan Am 103 Cvr Transcript
According to the official AAIB accident report (Report No: 2/1990), the CVR tape exhibited severe "dropout." The explosion had generated an immense electromagnetic field and physical shockwave that caused the CVR’s recording heads to momentarily lose contact with the tape. Furthermore, the forward cargo hold explosion severed electrical power lines to the cockpit milliseconds after the detonation.
After Lockerbie, the FAA and EASA mandated that all transport category aircraft be equipped with that are physically separate from the CVR’s power supply. Today, modern CVRs (now solid-state digital recorders) have independent backup power sources and hardened memory modules that can withstand explosive decompression and fire temperatures up to 1,100°C for 60 minutes.

The transcript reflects a professional, calm environment with no indications of technical trouble. The crew had just leveled off and were preparing for the oceanic portion of their flight across the Atlantic. According to the official AAIB accident report (Report
The noise appeared to come from a meteor-like object which was trailing flame and came down in the north-eastern part of the town. Air Crash Daily Pan Am Flight 103/Lockerbie Air Disaster Archives Today, modern CVRs (now solid-state digital recorders) have
Investigators from the Federal Aviation Administration (FAA) and the AAIB concluded that this noise was the sound of the explosion itself, which occurred in the forward cargo hold just below the cockpit. The blast was so powerful that it severed the electrical connections to the recorders and the rest of the plane's systems almost immediately.
