I was detailed to E 45 and had the pleasure of driving the green machine one day tour with war years boss Capt. "The Duke". I was used to driving E 88 which was an American La France then. The difference was acceleration. The ALF took off gradually like a bus, whereas the Mack wanted to "peel out" and take off. I had to make an adjustment pretty darn quick...
Detailed another time, I also received a company unit citation working back step with an outstanding "Eagles" crew with this rig.
