A fleet of various U.S. Air Force airframes find their landing spot together for the first time in history on a ramp at the Nebraska National Guard air base, April 4-11, 2020, in Lincoln, Nebraska. The fleet consists of a KC-46 Pegasus, a KC-135 Stratotanker, a KC-10 Extender and a C-5M Super Galaxy. The U.S. Air Force’s Air Mobility Command, in coordination with the University of Nebraska Medical Center and the Defense Advanced Research Projects Agency, conducted airflow tests on several different aircraft at the 155th Air Refueling Wing to assess measures to prevent aircrew and support personnel from contracting or transmitting the virus while transporting COVID-19 patients.
