Jack Loizeaux; Pioneer in Razing Buildings by Implosion

Jack Loizeaux, a demolition expert who was a pioneer of implosion--the use of explosives to collapse unwanted structures--has died. He was 85 and died Nov. 28 in Baltimore of a stroke. Loizeaux was a sort of architect in reverse, whose list of "shots," as implosions are called in the demolition trade, included major urban eyesores as well as landmark structures--several of Las Vegas' most fabled hotels among them.
