Clermont, Florida -- Twenty-one frantic families are sent scrambling as a building collapses around them: it's like some kind of Indiana Jones movie.
Those families say it's a humble hero, security guard Richard Shanley, who got them out alive when a sinkhole opened up underneath a timeshare resort near Disney World.
Shanley told 10 News he raced from condo to condo, hustling guests to safety as the sinkhole swallowed walls and walkways.

The roofline of the second story is now at eye level. Officials say it may topple further, because everything's leaning so much... but they think the sinkhole itself is now stable. Engineering crews will spend Tuesday testing to make sure the spread has truly stopped.

The Summer Bay Resort's CEO says families whose things were swept down into the chasm will be paid back, and while this cluster of timeshare condos remains evacuated, 50 of his property's 53 buildings are open and occupied.
The resort's owners say they plan to rebuild the destroyed units, but in a different area of the large property.
