Some of the earliest experiments in aerial refueling took place in the 1920s; two slow-flying aircraft flew in formation, with a hose run down from a hand-held fuel tank on one aircraft and placed into the usual fuel filler of the other. The first mid-air refueling, based on the development of Alexander P. de Seversky, between two planes occurred on June 27, 1923, between two Airco DH-4B biplanes of the United States Army Air Service. An endurance record was set by three DH-4Bs (a receiver and two tankers) on August 27–28, 1923, in which the receiver airplane remained aloft for more than 37 hours using nine mid-air refuelings to transfer 687 US gallons (2,600 L) of aviation gasoline and 38 US gallons (140 L) of engine oil. The same crews demonstrated the utility of the technique on October 25, 1923, when a DH-4 flew from Sumas, Washington, on the Canada–United States border, to Tijuana, Mexico, landing in San Diego, using mid-air refuelings at Eugene, Oregon, and Sacramento, California.

Similar trial demonstrations of mid-air refueling technique took place at the Royal Aircraft Establishment in England and by the Armée de l'Air in France in the same year, but these early experiments were not yet regarded as a practical proposition, and were generally dismissed as stunts.

night, low on fuel, with Cb's and nowehere to divert to!

Do aircraft being refuelled have an alternative (diversion) landing site in case of failure to refuel?

The Effectiveness of Black Buck

There has been considerable debate about the effectiveness of the operation. Some critics have described the contribution of the bombing runs as “minimal” (Ward, 1993). Although Mirage fighters were pulled back to Argentina following the raids, Argentine C-130s continued to use the runway at Port Stanley until the end of the war (White, 2012 Blackman, 2016).

The idea that the raids caused considerable fear of an attack on the mainland has been dismissed as “propaganda” by formal royal navy commander Nigel “Sharkey” Ward. In his 1993 work Sea Harrier over the Falklands, Sharkey states:

“The Mirage IIIs were redrawn from Southern Argentina to Buenos Aires to add to the defences there following the Vulcan raids on the islands. Apparently, the logic behind this statement was that if the Vulcan could hit Port Stanley, that Buenos Aires was well within range as well and was vulnerable to similar attacks. I never went along with that baloney. A lone Vulcan or two running into attack Buenos Aires without fighter support would have been shot to hell in quick time.”

In terms of the technical success of Operation Black Buck, there is considerable doubt as to the extent that the bombing raids actually made any significant impact on Argentine operations.

A United States Marine Corps study concluded that:

“The most critical judgment of the use of the Vulcan centers on the argument that their use was "...largely to prove [the air force] had some role to play and not to help the battle in the least." This illustrates the practice of armed services to actively seek a "piece of the action" when a conflict arises, even if their capabilities or mission are not compatible with the circumstances of the conflict. Using Black Buck as an example shows the effects of this practice can be trivial and the results not worth the effort involved.” (DeHoust, 1984)


Operation Black Buck was clearly one of the most ambitious combat operations in military aviation history. The skill of the RAF engineers and the bravery of the pilots and aircrew are made clear in the accounts of those who participated in the operation. Though the effectiveness of the operation is questionable at best, the success of such a complex and technically demanding operation means that Black Buck is rightly regarded as one of the Royal Air Force’s finest moments.
