The boom in luxury underground bomb shelters...which can have room for swimming pools, basketball courts...even a private jet!

It is the latest boom in real estate to sweep the nation complete with all the features of luxury living such as indoor pools, gyms, basketball courts and in some rare cases room for your private airplane.

The only catch is that the property is buried deep underground in bomb shelters designed to escape the apocalypse.

Once thought of as spartan concrete tombs where heads of state and concerned families could wait for the nuclear fall out to drop, bomb shelters have over the past 15-years become highly desirable - with developers rushing to offer custom installations.
