Keep in mind that a good underground bomb shelter is supposed to protect you even after a bomb explodes. It should protect you from nuclear fission and radiation, whose effects can still be felt even after several years. Your shelter should also be accessible from different parts of your place. People will be staying in the shelter for some time so make sure to provide good ventilation, ample storage areas, and comfortable living conditions. You can go as far as including an air filtering system that removes radiation from the air.

Yes they did work. The shelter had just the amount needed to make safe if inside. If a bomb were to hit the shelter it would miss. The likely hood of your shelter getting hit was impossible at that time.
speaking from experience from ww2 Southampton bombing raids; bombs traveling at or above the velocity of sound; make a screaming, or whistling sound. The better you hear them; the more certainty it is not falling on you. The one that hits you you will not hear; for it gets there before its sound. ----
Jackrabbits typically make their shelter in burrows underground, which they dig themselves or use abandoned burrows of other animals. These burrows provide protection from predators and extreme weather conditions. They line their burrows with grass and fur to make them more comfortable.
If you've ever seen a bomb you will notice that there are tail-fins. There are two purposes to these fins.To make the bomb fall where it is intended to go. Hitting a target with a bomb is a hard thing to do and a lot of technology goes into making a bomb the right shape to 'fall straight.'These tail-fins are also modified to make the screaming sound as they fall; to add a dimension of terror to a bombing raid.
An underground shelter is a good idea for tornadoes, but not for hurricanes. One of the main dangers during a hurricane is flooding, which would make underground the last place you want to be.
