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.

Oustanding views from homemade spacecraft!

This video features an American family that managed to send a balloon into space – up to 100,000 feet – and retrieve its camera which shot outstanding views from the upper stratosphere. Special thanks to Xavier (http://passiondesavions.blogspot.com) who provided the link to this amazing footage:
