The diminutive Bell X-1 rocket research plane was, of course, the world's first aircraft to break the "sound barrier" and achieve supersonic flight on Oct. 14, 1947. This aircraft was named by General "Chuck" Yeager after his wife as "Glamorous Glennis". The aircraft's conical nose, modeled on the lines of a .50 caliber bullet is clearly visible. This angle shows how it looked as it dropped from a B-29 before rocket firing almost 50 years ago.
