Well jdknasa98 has seen a lot of Hollywood movies?
Bombs do not arm automaticly due to a crash and detonate.
If the detonator does not go, the bomb will most likely not explode. Of course there are exceptions to the rule,
but these are rare.
Also in the case of a split open bomb casing, you have good chances that the tnt will just burn
and not explode.
I know that from experiance, as it used to be my job defusing and destroying WWII amunition during my time in the military.
