The lovely people at Lifeflight [www.lifeflight.co.nz] provided a medical equipped Metroliner SA227 for the day. Lifeflight are the operator of the Life Flight NZ Air Ambulance Service and the Wellington-based Westpac Rescue Helicopter.
Metroliner's [in general] has been have been variously described as "flying pencils" or a "rat with wings". Either way, I doubt you'd mind if you were in pain :-)
Anyway, here's the pictures. Unfortunately we could not get in [fair enough with all the gear in it] but I get the best inside shot I could.
