article_snippet: A collaborative team of scientists from nine institutions across Europe has designed a so-called Cruiser-Feeder concept that would allow planes to refuel in mid-air.
article_snippet: The system would involve a refuelling plane, carrying enough kerosene to top up to five passenger planes, located at various points along flight routes.
article_snippet: A collaborative team of scientists from nine European universities has designed A collaborative team of scientists from nine European universities Cruiser-Feeder concept that would allow planes to refuel in mid-air (illustrated).

article_snippet: the researchers have spent the last three years studying the feasibility of civil air-to-air refuelling operations similar to those used for military aircraft.
article_snippet: As the passenger plane approaches, the refuelling jet could take off, fly beneath the passenger plane before connecting specially-designed and made fuel tanks and pumps at targeted locations on the passenger plane (illustrated).
