Several investigations are underway into the helicopter accident that injured three spectators at the Salthill Air Show in Galway yesterday.
The injuries happened when a side-door fell off a British military helicopter and plunged around 150 feet to the ground below.
Three people - believed to be a Polish man and two Irish women - were hospitalised and were said to be in a stable condition last night.
The door fell about a hundred feet and three people were hospitalised with minor injuries as a result.
The Gardai, the Irish Aviation Authority and the British Government's Ministry of Defence are all investigating the incident.
