T dog........... .. .windup? coulbe. .. .You just cannot believe how many times I have been doing Mach .83 and some 747 has been above me at the altitude I wanted . Made me so angry I could have crushed a Rose. Just another Captain decision which I just hated to make. Slow to .80 or M.87?????. .Always, just because the co-pilot could not take command, I just had another cup of coffee realising I was making $ 3.67 an hour. Does this make me a bad person ?
