You mean, "Da--spasibo, comrade!" :-) Dave's drawing raises an interesting question, though:
Which Bumper round is it? The WAC second stage has a conical nose in the drawing, while the round (or rounds) in Peter's book have ogive noses (so does the one in Dave's attached photograph above). Bumper 4 was the famous 1949 White Sands vehicle that climbed 244 miles high (some books say 250 miles), while Bumpers 8 and 7 (launched in that order, after #7 sputtered on the pad due to faulty wiring) were the first rockets launched at Cape Canaveral, in 1950. Also, some of the Bumper photographs were retouched back then, probably for security reasons--on assembled vehicles, the protruding edges of the WAC fins were eliminated, and I wonder if the WAC nose cone might have been altered from an ogive to a true cone by the retouching, at least in some pictures?
