Eastern Air Lines Flight 935 was a scheduled commercial passenger flight operated by Eastern Air Lines. On September 22, 1981, the Lockheed L-1011 TriStar jet operating the flight suffered an uncontained engine failure which led to a loss of 3 out of the 4 hydraulic systems aboard the aircraft at an altitude of 10,000 feet (3,000 m) MSL. The crew were able to land the aircraft safely to an emergency landing at John F. Kennedy International Airport with some limited use of the outboard spoilers, the inboard ailerons and the horizontal stabilizer, plus differential engine power of the remaining two engines. There were no injuries.

The plane was a Lockheed L-1011 Tristar, registration N309EA, C/n / msn: 1010, fitted with Rolls-Royce RB211-22B turbofan engines, delivered in July 1972. In April 1973 and 1974, the plane was leased to Trans World Airlines under the same registration. It was en route from Newark Liberty International Airport in New Jersey to Luis Muñoz Marín International Airport, in San Juan, Puerto Rico.

The aircraft, N309EA, was repaired and returned to service until it was retired in 1988. In 1989, the aircraft was sold to Air Transat and re-registered as C-FTNB. The aircraft was scrapped in 2001.
