I work for a Charter airline that fly's DC-10's and 757's. We retired all our short ranged DC-10's a couple years ago. This plane was spared the scrapper for a little modification. The owner of our company teamed up with an engineering firm and modified it to a water bomber. It flew at the Paris Airshow this past year. These pics are from a Test flight we did for the FAA, US Forest Service, and Air Tanker Board. After this test the aircraft and the new company started to run it was certified by the FAA. It holds 12,000 gallons of water. Can drop all at once, several drops, or anything in between. Pictures were taken 150' to the side of the runway, aircraft at 145 knots and 150'.
