Digging for info - front drum explosion on 727s

Hello all, thanks to the internet a lot of us know that the factory front drum will probably come apart when the sprag fails. The driver has to be putting the pedal down while the transmission selector is not in 1st (no Low/Reverse band applied).

For all the drag strip failures, my question is this. Can these failures be tied to a valve body that didn't apply the low band in 1st?
