Digging for info - front drum explosion on 727s

I always do my burnout in second gear (manual valve body or trans brake valve body) then shift into high gear and always let off of the gas pedal (decelerate) when coming out of the water box. I always have a bolt in rear sprag and never do dry hops. In the 40plus years of drag racing I have never had a catastrophic transmission failure. If I brake a drive shaft / u-joint or rear gear I always dissemble the transmission and check the rear sprag for damage.
