LANSA Flight 508 was a Lockheed L-188A Electra turboprop operated as a scheduled domestic passenger flight by Lineas Aéreas Nacionales Sociedad Anonima (LANSA, a Peruvian airline company) that crashed in a thunderstorm en route from Lima to Pucallpa in Peru on 24 December 1971, killing 91 people – all six crew on board and 85 of its 86 passengers.

[clarification needed][2] LANSA Flight 508 departed Lima's Jorge Chávez International Airport just before noon on Christmas Eve on its way to Iquitos, Peru, with a scheduled stop at Pucallpa.

The aircraft was flying at about 6,400 metres (21,000 ft) above mean sea level when it encountered an area of thunderstorms and severe turbulence.

Some evidence showed the crew decided to continue the flight despite the hazardous weather ahead, apparently because of pressure to meet the holiday schedule.

[10] Koepcke's story was also told in the documentary film Wings of Hope (1998) by director Werner Herzog, who had narrowly avoided taking the same flight, when his reservation had been canceled due to a last minute change in itinerary.
