Virgil Hine and Frank W. Seifert completed the first successful aircraft-to-aircraft in-flight refueling when they transferred gasoline via gravity feed (meaning, without a pump) through a fifty ...

The Air Force said that on June 27, 1923, 1st Lt. Virgil Hine and 1st Lt. Frank W. Seifert, flying a U.S. Army Air Service DH-4B, passed gasoline through a gravity hose to another DH-4B piloted by ...

The KC-135, backbone of our tanker fleet, first flew less than 33 years after that initial demonstration of air refueling. It still fuels the freedom’s fight seven decades later, and will ...

Purdue University researchers are collaborating with NASA to study cryogenic liquids in zero gravity, leading to the possibility of propellant depots and refueling spacecraft in orbit. As we plan ...

In-orbit refueling was one of the experiments carried out over the past three days inside the Airbus A310 ZERO-G. Scientists have figured out a long time ago a way to carry out space-related ...

The skies over American cities will be filled with Air Force tanker aircraft on Tuesday to mark the 100th anniversary of the first in-flight aerial refueling in U.S. military history.

The $1.3 billion fleet of Pegasus air refueling tankers would replace the aging Stratotankers operated by the Maine Air National Guard's 101st Air Refueling Wing, also known as the MAINEiacs.
