Research into the Griffith-conceived laminar flow wing was conducted on this specially-modified Hurricane. To keep the surface as clean as possible, even the underwing roundels were painted inboard, on the centre section.
A Cessna L-19 with BLC and a cambered wing takes off in the Mississippi State University programme.
One of the earliest full-scale experiments into boundary layer control made use of the Miles M.6 Hawcon.

The de Havilland (Australia) G.2 glider modified to test-fly the Griffith-designed section, which had a suction slot well back on the wing chord.
The Armstrong Whitworth A.W.52 jet-powered flying wing was designed to achieve a high degree of laminar flow, although predictions were not realised.
First in a series of high-lift BLC experimental aircraft used by the Aerophysics Department of the Mississippi State University was this Schweizer TG-3A sailplane.
Two Douglas WB-66Ds were modified by Northrop in a programme funded by the US Air Force to conduct a full-scale investigation into suction-type boundary layer control. They were redesignated X-21As after modification.
The Mississippi XAZ-1 Marvelette was designed for a US Army-funded BLC research programme.
