The picture shows a hinge in the horizontal stabilizer indicative of being an elevtor. The elevator of the first X-1 was discovered in mid-flight to be useless at supersonic speed and Yeager only recovered control and saved the plane by clear thinking and judicious use of the trim function, which utilized moving the entire horizontal stabilizer.
The design was subsequently changed to make the entire stabilizer the elevator, and the "flying tail" was born.

I think Chuck Yeager also appeared in television commercials in 1988 endorsing George HW Bush on defense issues.

I was present October 14, 1997 for the 50th Anniversary flight. He did it in an F-15E this time, so it wasn't quite as tricky :)
I can remember him taxing past the crowd with the canopy open, waving at us. He pulled up and parked, and I thought someone would have to help him out of the cockpit. No way! They rolled up the ladder, General Yeager climbed down, put on his garrison cover and gave about five minutes of very appropriate remarks. Then he strode off into history.

The reason why the F-86 could safely exceed the speed of sound was the fact the plane had a "flying" horizontal tail stabilizer that was not affected by the shockwave of transonic flight, similar in design to the Bell XS-1 and the Miles M 52. There is no "official" proof that the F-86 went faster than Mach 1.0 before the XS-1 did but there are reports that North American test pilot George Welch did create sonic booms with the XP-86 prototype before Yeager's official flight on October 14, 1947.
By the way, the British did fly a scale model of the M 52 some years after Yeager's famous flight, and that research vehicle did exceed the speed of sound surprisingly smoothly, confirming that the "flying" horizontal stabilizer was the reason why the XS-1 succeeded in exceeding Mach 1.0.
