I was a pilot in the 20th during the period early December 1966 to late November 1967. When I arrived on station at Udorn around 1 December 1966, aircraft 676 was already painted flat black. The painting was done sometime prior to that, as was the upgrade of the engines and the redesignation as CH-3E on all of the aircraft. I was told that the engines were changed on station at Udorn. Apparently, that was considered to be of a routine nature.
