Me-263: The soviet I-270 (modified Me-263-copy) was unable to break Mach 1, but it was also a larger, heavier design with less thust and usual wing configuration. The critical Mach figure of the Me-263 is comparably low, the tailles design would be very problematic...
Me-P1101: Lacks thrust to overcome the drag at high subsonic speeds (maybe in a dive?), but still an interesting choice.
Ta-183: Lacks thrust as the Me-P1101, taildesign seems to be critical (not sure in this) in terms of statics.
delcyros said:I read it, too. There were many claims to have broken the sound barrier earlier than 1947:
1945: Highest recorded Me-163 (B) speed during interception (accidently): IAS(recorded): 1130 Km/h (in a dive, far beyond it´s critical Mach speed)
1945: Gerhardt Mutke at an Me-262 A dive, IAS(after Mutke): 1150 Km/h (also beyond it´s critical Mach speed)
late 1945: US pilots notes of the captured Me-262 include the following sentence: "...close to Mach speed you loose controll, the plane pitches down strongly. Once exceeded, you regain controll.."
1947: F-86 exceeds Mach 1 in a dive
1947: X-1 with civilian test pilot is said to have broken Mach 1
-None of these claims are confirmed by an independend source, but they remain very interestingly...-
1947: X-1, piloted by Chuck Yeager breaks Mach 1
FLYBOYJ said:George "Wheaties" Welch was the guy who broke the sound barrier the days before Yeager did it. I've heard stories that "Wheaties" was always bitter about his Air Force career and kind of had a chip on his shoulder. Put him together with the outspoken Yeager and you had a set-up for an argument. When I lived close to Edwards AFB a few years ago I heard from some old timers who worked at Edwards (Muroc) during that time that Yeager and Welch couldn't stand each other! The legend has it the Welch knew about the X-1 and record attempt and he went out over Edwards in an XF-86 and purposely broke the sound barrier, just to show Yeager up. It is rumored that the air force altered XF-86 test records by 7 months! Welch died a few years later testing the F-100. Check out this link: http://home.att.net/~historyzone/Welch2.html

Breaking the sound barrier in a dive would not really count anyway. Anyone could have done it. Just build a bullet shaped metal basket and drop it from 30,000 feet and walla - you will break the sound barrier - then release part of the basket at the nose with the weight in it, let the cockpit area slow down, and then deploy a parachute. But what would that prove?
Also, because of the airspeed indicator issues I listed above, readings in excess of mach 1 on the airspeed indicator were unreliable anyway.
