    but expect structural damage.

    CNOC took a 747 supersonic.  They flew it to Hawaii, but,
    i suspect that airframe was finished after that flight.

      that did this, I believe on the ground at San Jose. Supposedly it exceeded Mach in an unplanned dive. They pulled out, and got to San Jose safely. Apparently the wings are permanently bent, and the plane was never flown again.

      Nope... I got it all wrong.  Here is the wikipedia link. It was a 747, and it diverted safely to SFO, and was put back into service some time later.

      In a glider exceeding Vne is a really bad idea -- they tend to flutter, and things that flutter tend to come apart fairly quickly. In Cessnas, IIRC, Vne is usually related to bird-strike-on-the-canopy speed, so it might be less risky. Dunno about other aircraft.
