Narrative:
The EC-121 taxied out to the runway for a routine training mission. Then the left main landing gear suddenly collapsed and the left wing struck the ground. The aircraft started to rotate rapidly to the left and the right tip tank snapped off, rupturing the fuel tanks. A fire erupted and the aircraft was evacuated.

The gear reportedly failed due to stress corrosion.
