  1. Evanitis's post in How to do a proper reentry with a spaceplane? was marked as the answer   
    You are going too fast. You need to slow down before you hit the thick, lower atmosphere. First, your initial trajectory needs to be shallow. Lower your periapsis to ~40km, the friction will do the rest.
    What's more important, is to not face prograde during the descent. To bleed the most speed, you must present your widest profile to the airflow as soon as you reach the air (70km). Imagine throwing an umbrella closed vs. open. A forward facing aircraft is like the closed one. Pitching up to 90° is overkill in most cases, 30-40° should be enough. You can even trim the desired landing spot by holding a specific angle of attack (AoA).
    Illustration:

    It's possible that you can't pitch up. The most common reason for that is the CoM shifting behind the CoL while the tanks run dry, messing up your aerodynamic properties. There's not much you can do in this case besides redesigning, unless you have well placed control surfaces. In this case, you can try landing backwards. Sounds silly, but it's totally possible.
