Spotted this "10 Tanker Air Carrier" at Albuquerque Sunport (ABQ). Now used as a firefighter aircraft; note the bellypan.  Was originally delivered to Thai Airways International in 1987 as HB-TMB, then with Northwest Airlines from 1998 to 2006 as N239NW, then as a private air charter operator Omni Air International.
