As more paths become available to use between two points, the less likely it is that one or two simultaneous failures will prevent end-to-end service.

Despite the crew being trained and certified, no plan existed for the simultaneous failure of two engines on the runway, as it was considered highly unlikely.

It was the simultaneous failure in every market and governance area that we all rely on.

When the aeroplane suffered simultaneous failure in both its engines, forcing Bickerton to attempt a crash-landing.

In the most common case, the driver complains of a simultaneous failure of the brakes and sudden full-throttle acceleration.

The 410 is the first to employ two backup self-winding power storage units, and three separate pumps, rendering simultaneous failure a near impossibility.

The simultaneous failure of both recorders would strengthen the suspicion that the jet suffered a devastating electrical breakdown.

I can't imagine that happening except through gross carelessness or about three simultaneous mechanical failures.

But because the simultaneous failure of two engines seemed unlikely, there might have been a transmission or propeller problem.

In the event of simultaneous failures the most critical failure is displayed first.
