I thought the Norsk Helikopter was part of Bristows
as the colour scheme changed in recent years after taken over?
I remember they had a Leonardo da Vinci newsletter for download on the old Norsk site.
Also looking at the NHS web, the media gallery ,layout looks suspiciously like Bond Offshore and Air Services layout
Might see the new S-92 for Bond Offshore being unveiled next year at Heli Expo in Las Vegas?
