This 1972 built, US registered (Air-Serv International, Warrenton, VA) Twin Otter served the UNHCR in Chad. The Twotter was once registered VP-FAQ and painted in an all red color scheme while serving the British Antarctic Survey. It also flew in Norway as LN-FKB. But since 1988 it was registered to Air Serve and flew quite along time through the African continent. In 2013 it returned to USA and was eventually sold to a Mexican (XT-UTK) operator but is now back to its birthing-grounds, Canada as C-FZDQ flying out of Calgery.
