North American Rockwell OV-10 Bronco (N16854)

That has to be a blast to fly as a civilian. And expensive... I know it was used quite a bit in Vietnam, but outside of that, I remember it was pretty much gone from the inventory by the time I was in the Air Force in the 80s. I'm almost certain I got to work a couple as a tower controller though before they retired.

Read all about it: "A Lonely Kind of War: Forward Air Controller, Vietnam" by Marshall Harrison

"I picked the impact point I wanted for my rocket, then rolled the Bronco almost inverted and let the nose drift down toward the target. Reaching my left hand to the armament panel, I armed one of the four pods of white phosphorous (WP) rockets. I watched the lighted sight in my windscreen come to rest on the target; I neutralized the control forces, then quickly punched the release button on my control stick. I watched the single rocket start toward the target before I put the aircraft into a steep, climbing turn back to 1,500 feet."

Makes a good FAC for Firefighters as well.
