Couldn't find a specific section for the Observation types, but I would like to add that O-2 67-21300, registered as N590D, is alive and well in The Netherlands. The Postbellum Foundation (
https://www.stichtingpostbellum.nl/en) looks after the aircraft. Don't know a lot about the history apart from what's on the website:
Quote:
Our aircraft (registered N590D) was built in 1967 as the 6th O-2A to come off the line, and served for three years in Vietnam. After that she was flown back to the US, where she served until well into the 80's. She was when sold into civil hands. In the early 2000's the worn down airframe was fully restored to its original military state in Camarillo, California.
It arrived in The Netherlands after a ferry flight from the USA in early June 2013.

This aircraft is not listed so I will add it next time I update the O-2 section. Thanks!
