- Date: March 17, 1960
- Aircraft: Lockheed L-188 Electra
- Location: Tell City Indiana, United States
- Fatalities: 63
- Phase of flight: En route
- Cause: Right wing separated in flight from flutter driven by oscillations of the outboard nacelles, with reduced structural stiffness and severe clear air turbulence as contributing factors (CAB findings)
Northwest Orient Airlines Flight 710, a Lockheed L 188 Electra (N121US) flying from Chicago toward Miami, broke up in the air and crashed in southern Indiana on 17 March 1960. All 63 people on board were killed. Investigators found that the right wing failed because of whirl mode flutter linked to the outboard engine mounts.
