Hello all, We have a big fire east of me (The "Burro Fire") and since it has grown to more than 23,000 acres they have begun throwing their big gun at it. This is a modified DC-10 that carries 12000 gallons of a fire retardant slurry and during a pass it lays down a line approx. one mile in length. In Arizona, your typically fighting fires in or near mountains. I began seeing this DC-10 on approach vectors to this fire a couple of days ago. I have to say seeing a jumbo jet fly straight into mountains and disappear into them is amazing. Here is a short video of the types of passes this aircraft is making. This is precision flying in a jumbo jet. In many cases his ground clearance to wings or his belly is less than his wing span. These are a special breed of pilot who fly these firefighting aircraft.
