I'm sorry but I simply do not believe that the C-130 is capable of a 30° glide slope. That is 10 times the normal 3° glide slope.
I once spent two days in a simulator with FAA boffins looking at the maximum possible practical ILS glide slope and the answer was 7°.
If you didn't arrive at the glideslope intercept with the gear down, full flap, airbrakes out and flight idle then it was impossible to get back on the glide path.
A 30° slope is pure fantasy except in a Harrier or a helicopter.
