Original Note:
An aircraft would only be classed as supersonic if its airspeed was greater than the speed of sound. In this case, the aircraft was subject to a large tail wind and therefore, whilst its groundspeed was over 800mph, its airspeed would have been sub-sonic. https://en.m.wikipedia.org/wiki/Supersonic_speed#:~:text=Supersonic%20speed%20is%20the%20speed,%3B%201%2C236%20km%2Fh). https://www.grc.nasa.gov/www/k-12/airplane/mach.html
