Two people have been injured after part of a propellor smashed a window on a plane which had just taken off from Guernsey Airport. The Aurigny Trislander was 500ft in the air when flying glass from the shattered window sprayed passengers.
The plane carrying 12 to Jersey returned to Guernsey Airport.
Two people were taken to the Princess Elizabeth Hospital. One was treated for cuts and one may need surgery on an injured hand.
'Rare occurrence'
The plane landed safely before checks revealed the damage was caused by a rubber anti-icing cover from the propeller.
An incident has been described as one of the most serious in the airline's 36-year history.
The Air Accident Investigation Brance and police were looking into the matter.
Aurigny financial director Peter O'Donovan said: "We will also carry out our own investigation into this very, very rare occurrence."
