Anyone know what type engines Longtail operates?
Also, despite the headline, I'm not sure that was 'technically' an uncontained failure. Bits coming out the back of the engine are not considered to be 'uncontained' as they come out at relatively low velocities and are unlikely to do damage to the aircraft structure.
"Uncontained" generally means high energy pieces coming out the side - tangential to the axis of the engine.
