The 1921 V.B.L.-1, built by Aerial Transport Corp, was an open cockpit biplane described as an “express transport of three-ply construction.” 1922 Eaton Chronicles reported that Rogers Construction Co “… takes over the building of a Sport Biplane designed by C H Day of the defunct Aerial Transportation [sic] Corp.” Then in 1925, “Charles ‘Pop’ Dickinson buys the C D Air Express from Rogers,” which is described as a C H Day design. This would be conclusive proof that VBL-1 and CD Express are one and the same.
