Sloanes had the maint contract for a while
I saw white / grey ZE177 (?) inside their new hangar over 10 years ago
and even close up looks like any civvy machine bar the oomps and wee bumps on the fuselage lol
Single pilot operated IIRC when looked in the cockpit looked no different to say a police machine tbh. Didn't see in the back
Cheers
