Titanium is ideal for camping cuttlery and mugs because it is si light and strong.

It is also used for the fuselage of fast jets to reduce mass and improve performance. Titanium is the main metal in the fuselage of the SR-71 Blackbird--a reconnaissance plane that flew above 18,000 m (~60,000 ft). and at speeds of Mach 3. An SR-71 flew across the United States in a record-setting flight from Los Angeles, California, on the west coast to Washington D.C. on the east coast on March 6, 1990--a distance of 3,700 km (2,300 miles) in ONE HOUR AND FOUR MINUTES (64 minutes). This is an average speed of 3,418 kph (2,124 mph) - mach 2.77 average (2.77 times the speed of sound).

The image shows an SR-71 on display at the Smithsonian National Air and Space Museum, Steven F. Udvar-Hazy Center in Chantilly, Virginia, USA 39 km (25 miles) from Washington D.C.

Concorde, the supersonic aircraft, has titanium in many areas in its construction including a stainess steel and titanium skin. The tail in the photo is on 002 prototype --for test flights--on display at the Fleet Air Arm Museum in Yeovilton, UK. You are able to walk thriught he aircraft. You can also go into a Concorde, for the "Concorde Experience" previously in British Airways service at the Brooklands Museum in Weybridge, UK and see an Air France Concorde at the National Air and Space Museum, Steven F.Udvar-Hazy Center in Chantilly, Virginia, USA
