Flightnumber: 143
Narrative:
Ambient air temperatures were high - 95░F (35░C) - as the Boeing 737 was parked at Manila. The air conditioning packs, located beneath the center wing fuel tank, had been running on the ground before pushback (approximately 30 to 45 minutes). The center wing fuel tank, which had not been filled since March 9, 1990, probably contained some fuel vapors. Shortly after pushback a powerful explosion in the center fuel tank pushed the cabin floor violently upwards. The wing tanks ruptured, causing the Boeing to burst into flames. The vapors ignited probably due to damaged wiring, because no bomb, incendiary device or detonator has been found.
