Gary Lynch, the general manager of Texas-based Rising S Co., told The Sun that underground doomsday bunker demand is up more than 1000% since Russian troops invaded Ukraine on Feb. 24. 

"Typically, I'll sell between two and six shelters a month - and usually winter is a quiet time for us.

"But I sold five units alone on Thursday, and I've sold two more already today - there's no telling how many more [orders] we will get.

"The phone hasn't stopped ringing, and we've been sending out so many quotes," added Lynch.

Readers may recall hearing about Rising S in the early days of the COVID pandemic and social unrest as underground bunkers were in high demand.
