Would it be reasonable to expect the Shenzhou desent profile to be similar
to Soyuz? I guess from an aerodynamic point of view there can't be much
dufference since the modules are quite similar in size and shape? What is
the approx timespan from de-orbit burn completion until touchdown of Souyz?

BTW: Xinhua reports at 2137 GMT that SZ5 has performed the initial maneuvers
prior to de-orbit burn. According to some sources touchdown is expected
approx 2230 GMT.
