Skadi, thanks for the info.
Apparently, Irish Helicopters Ltd have been serving the Commissioners of Irish Lights for 39 years now. They started with the Alouette III (EI-ATO and EI-AVI), then a host of BO-105s (EI-AWB, EI-BDI, EI-BLD, EI-BTE and EI-LIT) and now this EC135. I have been doing some research into the past IHL fleet and apparently a Hiller UH-12 was trialled by the Commissioner of Irish Lights in 1959. The CIL people didn't think much of the Killer-Hiller and didn't enter into a contract. That Hiller was registered to a company called Irish Helicopters and was sold in 1960. No other helicopter was registered to IHL again until 1968 (on the Irish Register, at least), so I'm not sure if the people behind the Hiller were the same people that started ops in '68. In 1966, the Shannon-based company Trans World Helicopters also did some work for the CIL, with a float-equipped Hughes 300.
Irish Helicopters Ltd is also celebrating 40 years of operations this year, so well done, Lads.
