Then the earth shook and trembled; the foundations also of the hills moved and were shaken, because he was wroth. And he rode upon a cherub, and did fly: yea, he did fly upon the wings of the wind.

A high resolution image of Boeing XB-29, S/N 41-0002, the first prototype of the B-29 Superfortress, seen at Boeing Field, Seattle, 1 October 1942. The first three aircraft built, most notably sporting three-blade propellers, would be designated as XB-29s, later models being of an improved version designated YB-29s. Only these first few, along with the early Wichita-built airframes would be delivered in distinctive olive-drab and gray camouflage schemes.
