Hi Joey,

    If you want the fastest plane available, your best bet is probably going to be the SR-71 Blackbird. Just keep in mind, you get up around 80-90K in alt, and mach 3.5+, stability is going to become a MAJOR factor. You just can't hit those hypersonic speeds at lower alts, and when your that high up, your angle of attack is so high due to the thinner air that your flight controls start to get pretty funky.
