Was a hydrogen-filled, rigid airship which operated commercially from 1928 to 1937. During that time it made 590 flights and flew more than a million miles. The Zeppelin could achieve a top speed of 80 mph (70 knots) at its maximum thrust of 2,650 horsepower and had a useable payload of 15,000 kg (33,000 lbs).
Is a family of single-seat, single-engine, fifth generation multirole fighters that are designed to perform ground attack, reconnaissance, and air defense missions with stealth capability. The F-35 has three main models; the F-35A employs conventional takeoff and landing, the F-35B will be used for short take-off and vertical-landings, and the F-35C will be carrier-based. The F-35 models are intended to provide the bulk of tactical airpower for the U.S. Air Force, Marine Corps and Navy over the coming decades.
Is a 1930s biplane designed by Geoffrey de Havilland and was operated by the Royal Air Force (RAF) and others as a primary trainer. It is a very easy plane to fly with a stall speed of only 25 knots. However, it has no electrical system and must be started by hand.
Mars Exploration Rover NASA's twin rovers, named Spirit and Opportunity, launched separately in 2003 and landed three weeks apart in January 2004. They made important discoveries about wet environments on ancient Mars that may have been favorable for supporting microbial life. Although Spirit ceased communicating with Earth in March 2010, Opportunity continues its work on the Red Planet.
