Southwest Airlines Flight 611 departed Naha runway 36 at 13:09 for a regular flight to Ishigaki-Shima. The aircraft climbed to the cruising altitude of FL240. At 13:33 the crew were cleared to descend to 8000 feet and after that to 3000 feet. Approaching 3000 feet, the crew were given weather information for Ishigaki: wind 300deg/12 kts; temperature 32deg C; active runway: RWY22.
The 737 made a crosswind landing, with the speed at touchdown 6 knots above Vref. The aircraft bounced and landed back. When the spoilers and reversers didn't seem to operate, the crew shut down both engines, thus making it impossible to use the anti-skid system. The inner tyres on both main gear legs burst almost simultaneously at 125 m short of the runway end. The aircraft skidded to the left, overran the runway and came to rest 145 m further on. At 14:01, after everyone on board had been evacuated, the aircraft caught fire.
