Afaik a 747 went into a steep dive snd reached Mach 1.2 before the pilots managed to pull out. Landed somehow safely. Plane had to be scrapped as the wings were bent upward due to overload.
Amazing not only that the 1.01 Mach airspeed did not exceed VNO but that the same aircraft was then sold as new and operated for years as a commercial airliner. Any turbulence at that limit is big trouble as noted above. Hydraulics exceed capacity and control surfaces no longer function because of the shockwave. They must have had perfect weather.
