The Whitley was most certainly NOT the first aircraft to fly with variable pitch propellors. The Douglas DC-2, which first flew on May 11, 1934 (two years before the Whitley), had them. Douglas DC-2 Jdoniach ( talk) 16:34, 23 November 2023 (UTC) reply

The source cited for that statement says "...was the first aircraft to fly with de Havilland tree-bladed two-position variable-pitch airscrews." which suggests that the claim is specifically restricted to de Havilland vp-props rather than those by other companies - experiments were made with variable-pitch propellers as far back as WW1.
