On a standard Boeing 737-800, you will find a total of four overwing emergency exits, with two located on each side of the aircraft. These exits are positioned directly over the wing structure to provide a stable platform for passengers during an evacuation. These are "Type III" exits, which in older models were removable hatches that had to be pulled inward and tossed outside, but in many modern 737-800 "Next Generation" (NG) and MAX models, they are "swing-out" or "spring-loaded" doors that open automatically outward and upward. This design is crucial for meeting the FAA's "90-second rule," which requires a full aircraft to be evacuated in under 90 seconds using only half the available exits. Passengers seated in these rows (usually rows 14 and 15 or 15 and 16 depending on the airline's configuration) must be "able-bodied" and willing to assist in an emergency, as they are responsible for operating the heavy door and directing the flow of traffic onto the wing and down the integrated escape slides or marked paths.
