The SNA departure was more like an airshow. Combined with the steep pitch (22-24deg) and the immediate cutback on power to quietly exit the area, we were required to brief the passengers on the very unusual departure. The difference in noise from climb power to cutback sounded like the engines had flamed out..
The concern a lot of crews had was what would happen if you had a catastrophic engine failure with the nose parked up at 20+deg and just about when you were doing the cutback.
For normal ops, we were limited to 20deg pitch.
