2nd fuselage with a hole – Southwest Airlines aircraft grounded

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 main rotor or rotary wing on the H-3 has five identical wing blades. Other helicopters may have two, three, or four blades. A typical wing blade is shown in figure 1-17. The rotary-wing blade is made of aluminum alloy, except the steel cuff by which the blade attaches to the rotor hub. The main supporting member of the blade is a hollow, aluminum alloy extruded spar, which forms the leading edge. The steel cuff is bolted to the root end of the spar. Twenty-three individual pockets constructed of aluminum ribs, aluminum channels, and aluminum skin covering are bonded to the aft edge of the spar.
