The Jaguar, if clean, was supersonic at low-level. I should know. Shall not say where though
The VC10 has gone supersonic, though in error. Crossing the Pond at speed with the Flt Eng off the flt deck, then passing thro a front resulted sometimes in a big change in temperature which resulted in s big speed jump. Though the mach warning horn would have sounded, unless of course a naughty man had pulled the cb.
