2 years ago I was descending into Milan Linate at night from the North having just crossed the Alps in the airway at FL150. As I passed 5000 ft I began to smell burning and was rather concerned about the possibility of an engine fire, I couldn't figure it out - all the gauges were fine and the engine sounded perfect.
