Boeing KC-135 Stratotanker
It is difficult to refuel strategic bombers, but the KC-135 Stratotanker can definitely do the job. During the Vietnam War, the Americans used this aircraft heavily, and during Operation Desert Storm, it was a significant strategic asset. The Boeing 367-80 was developed into the KC-135 and the Boeing 707. The Boeing KC-135 is 136 feet long and was revolutionary because it was the first jet-powered refueling tanker of the United States Air Force.
NASA Super Guppy
This plane replaced the Pregnant Guppy. This was the first Guppy aircraft that Aero Spacelines produced. A glance at the plane will tell you that it was made for cargo. There were five planes built for each of the two variants of the Guppy, which were named “Super Guppy.” Today, all of the planes are still in service. We don’t think there is a need to explain how the plane got its name because it’s pretty self-evident.
