- Ariane 501: About 40 seconds after initiation of the flight sequence, at an altitude of about 3700 m, the launcher veered off its flight path, broke up and exploded.
- Mars Pathfinder : An erroneous implementation of the shared memory caused a priority inversion. An unexpected reset occured.
- Mars Polar Lander: The mission ended in failure with the loss of the craft in an incident. The cause of the communication loss is not known but NASA stated that the vehicle did not survive the descent.
