United States Air Force C37A [Gulfstream V] visitor

I arrived out at the Aero Club earlier today for the planned trip to Omaka [more details in the next post] and spotted this USAF aircraft parked on the RNZAF Air Movements Base apron.

I believe that this is a C37a [based on the Gulfstream V]. I manage to get a few pictures, but none of the departure around 11:15am, as I had just left as a passenger in a Piper PA28-181 Archer. I may be able to score some pictures of the arrival which I'll post later when/if received.
