Context:

A severe storm at Atlanta's Hartsfield-Jackson International Airport has led to the cancellation of over 450 flights and delays of hundreds more during the busy Fourth of July holiday travel period. Delta Airlines, which uses Atlanta as its hub, faced significant disruptions with 14% of their flights canceled and over 100 aircraft requiring inspection due to quarter-inch hail. Powerful winds forced the evacuation of most air traffic controllers from the control tower, leaving a small crew to manage inbound flights. A ground stop was implemented, further compounding delays as millions are expected to travel over the holiday period. The airport, one of the busiest in the world, anticipates nearly 400,000 passengers during this period, as Delta's maintenance team works swiftly to address the backlog caused by the storm's impact on operations.
