When I was still in Seattle, we would get periodic appearances from Metrea and their KC-135s. They would provide tanker support to the US Navy. That they operated from Boeing Field rather than going to a Navy base was always welcome. I didn’t know much about Metrea other than that they provided tanking services. However, they showed up at RIAT with a couple of their other types.

They brought a pair of turboprops. The King Air was in a low-key grey paint scheme and didn’t have many conspicuous external additions. There were some antennae that suggested extra comms capabilities and some ventral fins that imply something else might get added that reduces directional stability.

The Dash 8 had a bit more of a colourful paint job. A grey base livery but some red and yellow stripes brightened things up a bit. It similarly didn’t have anything too conspicuous added while it was flying but, when it was on static display, there was a turret under the front fuselage. There was another Dash 8 which did have some sensors which will get a post at some point.
