New aircraft were required to be tested or “slow timed” prior to use in combat, and this photo of Maj. Charles N. Keppler’s P-51D “Miss Margie”, 44-63173, E2:L, taken near Chievres on 8 March 1945, illustrates the wisdom of this practice. The diary of 375th pilot Lt. Robert J. Farney described it thus: “flew Major Keppler’s ship for 30 minutes and when the engine practically quit, I made a forced landing down wind. I ended up down the lot and tore the plane all to pieces. What a day.”(Pearce)
