A Lloyd Aéreo Boliviano Boeing 707 crashes after takeoff from El Trompillo Airport in Santa Cruz de la Sierra, Bolivia, killing 91.

Lloyd Aéreo Boliviano (LAB), internationally known as LAB Bolivian Airlines, was the flag carrier and principal airline of Bolivia from 1925 until it ceased operations in 2010. It was the second oldest airline in South America after Avianca, and among the oldest airlines in the world. It operated scheduled domestic and international services to destinations in the Americas together with a transatlantic route to Madrid in Spain. It was headquartered in Cochabamba, having its main domestic hub at the city's Jorge Wilstermann International Airport, and international hubs at Viru Viru International Airport in Santa Cruz and El Alto International Airport in La Paz.

The Boeing 707 is an early American long-range narrow-body airliner, the first jetliner developed and produced by Boeing Commercial Airplanes. Developed from the Boeing 367-80 prototype, the initial 707-120 first flew on December 20, 1957. Pan Am began regular 707 service on October 26, 1958. With versions produced until 1979, the 707 is a swept wing quadjet with podded engines. Its larger fuselage cross-section allowed six-abreast economy seating, retained in the later 720, 727, 737, and 757 models.

On 13 October 1976, a Boeing 707-131F, a chartered cargo aircraft operated for Lloyd Aéreo Boliviano (LAB) crashed shortly after takeoff at El Trompillo Airport, Santa Cruz de la Sierra, Bolivia, into a residential neighbourhood. All three crew on board were killed, along with 88 other fatalities on the ground, bringing the total up to 91. It is the deadliest air disaster to happen on Bolivian soil.

El Trompillo Airport is located in the south part of Santa Cruz, Bolivia, about 2 km away from the central plaza.
