The Bellevue Police Department in the US state of Washington received an unusual call: Could they come check out a military-grade rocket in a garage? The Seattle Times reported. A Bellevue man bought a rocket from an estate sale. After he died, his neighbor called the National Museum of the US Air Force in Dayton, Ohio, asking if the rocket could be donated. The museum called Bellevue police, who went to the residence and found the rocket was a Douglas AIR-2 Genie, an unguided air-to-air rocket that is designed to carry a 1.5-kiloton W25 nuclear warhead. Bomb squad members confirmed the rocket was inert, meaning it contained no rocket fuel. No warhead was attached. This type of rocket was used by the U. Air Force and Canada during the Cold War and was the most powerful interceptor missile ever deployed by the Air Force, according to Boeing.
