I just noticed that my other blog post went way off. As someone did say, Stark Industries made the missil(can't spell) hit the Maximoff's home, and Tony Stark almost got blown up by a bomb made in the same place!

Tony Stark didn't blow up the Maximoff's apartment, but the evil dessert people who stole Stark's weapons in Iron Man blew it up, because remember what the leader of those bad guys said? "Welcome to the biggest mass killing made in history" Bla Bla Bla, so they fired some of the missions before Stark escapes by making an Ironman suit and blasting himself out, so he knew nothing about the bomb exploding the Maximoff's home.
