Really good documentary on the 1980 accident.Smitty-48 wrote:The danger was not impact, the danger was heat, the heat wave from the explosion reaches the circuit before the blast wave, fuses the circuit, and that fires the detonator, the fact that it popped straight off and flew clear of the heat; just dumb luck.
Let's say the first stage collapses on an angle, buckles sideways instead of straight down, so the warhead doesn't pop straight off but gets driven into the side of the silo instead; cooks off in the heat, when the circuit fuses.
Every single strategic warhead you have in the inventory now, has built in safety systems to prevent this, ENDS, FPS, IEM, etcetera, but the W53 in 1980; didn't have any of them.
You can watch it for free.
