Currently, satellite technology company Row 44 uses an HU-16B Albatross (registration "N44HQ") to test its in-flight satellite broadband internet service. Purchased, restored and named Albatross One in 2008, the company selected this aircraft for its operations because it has the same curvature atop its fuselage as the Boeing 737 aircraft for which the company manufactures its equipment. The plane purchased by Row 44 was used at one time as a training aircraft for space shuttle astronauts by NASA. It features the autographs of the astronauts who trained aboard the plane on one of the cabin walls.
