That's the point where you do an OPS transition and change from entry guidance to TAEM guidance (which works rather differently). While entry trajectory control is really different from the way an airplane is flown, during the TAEM pattern the Shuttle resembles a supersonic airplane. But that's for a different tutorial. You can still switch off AUTO control of the pitch channel and try to fly to the runway on your own.

* If you get much below the nominal trajectory, you need to aim at the target at the first reasonable opportunity (perhaps around Mach 14 when you have plenty of speed left and the Shuttle actually can already change direction) and otherwise fly zero bank angle for optimum glidepath. If you aim too early, it costs a lot of lift without changing direction, if you aim too late the additional distance you have to fly due to the azimuth offset is too large.
