Wreckage is what is left after something is destroyed. Sift the wreckage, pulled from the wreckage, the wreckage of a career.
It is a mass noun with no plural, so it is a lot of wreckage rather than many wreckages. It applies to lives and plans as readily as to aircraft, and the figurative use is common enough that nobody notices it is a metaphor.
