G'day, I believe it's a Marchetti 260 with a Turbine conversion. I haven't seen a turbine one of these, and it looked awesome in the movie. Not sure who operates them tho.
The flight scene was great, up until he pulled it into the longest vertical climb and had enough time to grab a chute for his girl and get out the back in time for it to fall away. Lets see all you parachutists do that one, especially in a DAK.
