An exciting challenge, a satisfying building experience, and a dazzling result – that’s METAL EARTH models! Building a METAL EARTH 3D puzzle requires patience and dexterity. The finished model fully rewards the effort! The miniature replicas make an especially striking and eye-catching decoration not only at home, but also in the office or at school. From square steel sheets (11 x 11 cm) featuring parts of world monuments, famous vehicles, musical instruments, or animals, you’ll assemble finely detailed, fascinating models. The authentic look of METAL EARTH 3D puzzles is achieved through precise laser engraving. The package includes 1 steel sheet with parts and assembly instructions. Tools are not included. WORK PROCESS: Remove the individual parts from the metal sheets; if needed, use small snips (not included). Parts connect using tabs and slots. Bend the tabs with small needle-nose pliers (not included) and gradually secure all connections to create a highly realistic masterpiece! Recommended age: 14+. The Lockheed SR-71, unofficially known as the Blackbird and nicknamed Habu by its crews, was an American strategic reconnaissance aircraft noted for its high speed at extreme altitudes. It was designed for flight up to 25 km and speeds around 3,000 km/h, using primarily titanium so the airframe could withstand temperatures up to 300 °C. The Blackbird also holds numerous records: on July 27, 1976, the crew of Joersz and Morgan reached 3,529.56 km/h in an SR-71A, a record that still stands for the fastest air-breathing manned aircraft. Only rocket-powered craft have gone faster within the atmosphere. Another record was a transcontinental flight across the United States on March 6, 1990, covering 3,869 km in 67 minutes and 54 seconds, with an average speed of 3,419 km/h. The trip from Los Angeles to Washington, where the aircraft is now displayed at the local airfield museum, took just 64 minutes and 20 seconds. No SR-71 was ever shot down.
