Walmart's futuristic plans to deliver your orders via flying robots are closer to becoming reality, as the mega-retailer expands its drone delivery program to five major cities and more than 100 store locations.

Walmart and Wing are expanding their partnership and rolling out drone delivery to dozens of more stores in Atlanta, Charlotte, Houston, Orlando, and Tampa.

The big-box retailer has already tested drone deliveries in Arkansas and expanded them in the Dallas-Forth Worth area.
