This is a "coke wash" cleaning of a DC-10 engine in progress. Running the engine at idle, a technician will direct a spray of mild abrasive into the engine to clean off deposits that can cause high heat (EGT). Note the technician is tied to a tug for safety.
My question: "coke wash" cleaning still in progress anywhere today? I never see anything like this before.
