Joplin, Missouri hit the headlines for all the wrong reasons back in May when it was ravaged by a giant tornado that killed 162 people and destroyed an estimated 2,000 buildings.
As survivors reeled from the catastrophe they got some good news from the 'Extreme Makeover: Home Edition' gang, who announced they would help rebuild homes for some of those dispossessed by the tragedy.
In what producers say is one of the largest projects ever undertaken by the reality show, 'Extreme Makeover: Home Edition' started work Wednesday on the ambitious plan to build seven houses in seven days.
'Good Morning America' host Sam Champion was on hand to reveal the names of the deserving families -- some of whom lost children in the disaster -- who will benefit from the new homes. 'GMA' will be reporting on progress throughout the week leading up to Ty Pennington's "Move the bus!" on Oct. 26.
