Yes there is plenty of life in the old machine [it is quite a youth when compared with the Chiltern AS355F1 that was sold on May 1] but like all the older generation aircraft it is gasping to carry the role load. In addition it is now also covering Cumbria [shared with North East] so the speed and additional range will make their interventions more meaningful.
Come back in five years and we can probably discuss the delivery of the first police EC145 [or even a Merlin!] .... it is only a matter of time before the EC135 is also gasping to carry the ever increasing load.
As for 'super quiet' ...... we are talking about a helicopter arn't we ...?
