airships

In the 1920s and 30s,during 'coastdown' tests of Paul Jaray's- designed Zeppelin LZ-126 (USS Los Angeles),Wolfgang Klemperer and NACA (NASA) testers had to include this mass of air which traveled along with the airship in the drag calculation.
19th-century race hull designers observed it on ships.
Railroad train drag testing reported on such a thing with respect to the boundary layer.
Hucho has a section on 'convoy' driving which doesn't directly mention a 'corridor effect',although it would be embedded within the phenomenon.
