Aircraft owned and operated by Aramco. Originally delivered to TWA as N8731 in 1969 and acquired by Aramco in 1981 and eventually sold in 1985 and converted to a KC-137E for the Spanish Air Force as T.17-1 and later on TK.17-1.

Built in 1952 and supposedly named The Flying Camel, but no sign of that here. In August 1961 it became SE-BDY with Transair Sweden who leased it to the United Nations. On 18 September 1961 it was destroyed when it flew into terrain on approach to Ndola, Zambia (FLND) while carrying the then UN Secretary-General, Dag Hammarskjöld.
