#4: TWA Flight 800 (1996)
Just minutes after departing New York for Paris, the plane exploded in midair off Long Island. The 230 people onboard were killed instantly as wreckage plunged into the Atlantic. Eyewitnesses reported seeing a streak of fire, fueling speculation of missiles or terrorism and keeping the nation on edge.

After years of investigation, the cause was traced to a fuel tank explosion sparked by faulty wiring. The tragedy prompted redesigns of fuel systems to prevent similar disasters. Conspiracy theories lingered, but the true legacy of TWA 800 is the push for safer electrical and fuel protections on modern jets.
