I think you misunderstand my post. The IT failed at the Drive Arm, This left the Disc rotating with its full energy in an out of balance fashion. This is not the first time an IPT has fractured fully from its Drive Arm. The idea is that the Disc would burst and exit with or without the Stall. Forget the Stall. The moment the disc parted its Arm, the clock was running. As the Turbine lost its blades having migrated into the Stator, N2 diminished. At perhaps five hundred pounds and 7500 RPM, the Burst was on its way. A Stall makes the bang, one of two. I list the Stall as the first bang. It could have easily been the second loud report. No need to link the Stall with the failure,[I] if indeed there was a Stall. If there was, it isn't round the bend to think it may have tipped the Disc, aggravating and perhaps speeding the Burst along?
The explosive disintegration of the Wheel is seen. What on Earth does 9/11 have to do with this?? The Disc is 'very stout' therefore it withstands the forces that fail it, ipso facto?
