Once had 417 GS in a BE20 from UTTT to UBBB at F280, picked up the jetstream that happened to be going my way, desent was interesting, power off, nose down VSI off clock and controler even asked if i could reduce GS....
UBBB was interesting, passing 1500m encountered the worse turbulance, windshear and icing I ever had. wind went from aprox 280 to 020 in about 1000 ft, ILS to minima and wind on landing around 60kts gusting 70 straight off the caspian sea, made one of the shortest landings ever in a kingair... As for the way home, well what you win on one you lose on the other....
