Warning alert on two North Sea helicopters in space of three days

[mhm]

A warning alert appeared on two helicopters in the space of three days just weeks after an aircraft ditched into the sea off Shetland killing four people.

The Bristow-operated Sikorsky S92 chopper was 90 miles off the coast of Scotland on Saturday morning when an indicator flashed, forcing the pilots to head straight back to Aberdeen International Airport.
