United Nations Pilot Grouping

Recently acquired this grouping to a US United Nations Pilot, Captain Skip Doney.  Unusual, different but interesting grouping.  As you can see brass badge also says he was a member of the US State Department.  Also of note is at the bottom of the badge is a small United Nations Korean War service ribbon.  I'm guessing this lot may be from the late 50's-60's era, the height of the Cold War.  A US pilot flying around the world under the umbrella of both the United Nations and US State Dept., wondering if there might be a CIA connection also, hmm.  I haven't tried to research Capt. Doney yet.  Thanks for looking.
