I noticed in the video footage of the PM running down the ramp door to escape the aircraft, that the slow-moving ramp door was fully open when the footage started, with other persons moving around the rear of the aircraft! My point is this looks to me like a media 're-run' of the evacuation for the benefit of the cameras!
Anyway, it was a J-model C130, who knows what happened aboard, certainly not the pilots, and since there is no Flight Engineer on this model, I thinking nobody knows whats happening when something goes amiss, as it did this day!
