The US Air Force has celebrated the 60th ‘birthday’ of the Boeing KC-135 Stratotanker. The first example of the tanker flew in August of 1956 and was delivered to the USAF in June the following year.
Strategic Air Command had the KC-135 in service from 1957 to 1992. Following the inactivation the command in 1992, most KC-135s were reassigned to the newly created Air Mobility Command. A few of the records broken by the type include the most distance covered in a closed-circuit without refuelling, highest speed for 2,000 km (1,242 miles) and highest speed for 5,000 km (3,106 miles).
