10 Tanker Air Carrier has posted some photos on their web page of their third DC-10 air tanker that is under conversion. They expect it will be complete by mid-summer. The aircraft has been added to the exclusive use contract, along with Tankers 910 and 911.
Below is a really shaky cell phone video of one of the DC-10s dropping on the Miguelito Fire at Camp Pendleton in southern California, May 16, 2014.
