A Southwest Airlines Boeing 737-3H4 had been forced to make an emergency landing less than two years ago. Another B-737-3H4 has just had a 6′ hole in its fuselage during a flight causing sudden decompression, and emergency landing.
The NTSB is leading an investigation into exactly what happened to this Southwest Airlines flight – a 737 which had a hole come open during a flight from Phoenix to Sacramento at FL 360 (altitude: 36,000 feet that is to say almost 11 kilometers high). It was a harrowing experience for the passengers and the crew members. Watch the video:
The VASI (Visual Approach Slope Indicator) and the PAPI (Precision Approach Path Indicator) are systems of lights that provide guidance information to help pilots acquire and maintain the correct approach to an airfield. They are generally located beside the runway. These lights can be seen from up to 8 kilometers (5 miles) during the day and up to 32 kilometers (20 miles) or more at night.
