Ka-2b pilot, kerosene's vapour is not flammable like petrol's is.
dsc810, many years ago we had a reheated Spey let go of it's HP disc and it exited at 7-0-clock, chopped through the test cell's main fuel inlet pipe, hit the floor, ran up the test cell wall like a Catherine wheel, along the ceiling, down the opposite wall and buried itself into the substantial steel test cradle. The resulting fire was spectacular and the cell out of commission for weeks. And that's with a small engine. A modern large bypass engine's disc failure is a sight to behold!
