You may find that the interest may be generated from Air Ambulance operations that are seeking alternatives to the EC135, which is an OK all rounder, but not the perfect AA platform. Certainly the MD902 (with better support from the manufacturer) is giving it a run for its money, albeit still not the perfect machine.
So if any of their customers are renewing their contracts in - say - 2010, they might be asking for alternative platforms capable of - say - night operations, for which the 429 may be more suited than the EC135. Maybe.
Bond's customers may be charities, but they ain't run by idiots. They are generally run by people who know what they want. And Bond are being reactive to the market demands.
