In Revelation Space, Volyova puts the Nostalgia For Infinity into reverse at 10 g acceleration. This saves her life because she's falling down an elevator shaft at the time. It also kills Nagorny who hits the ceiling at high velocity. Somehow everyone in reefersleep survived - possibly reefersleep caskets are damped to permit high acceleration. Did I miss exposition somewhere that accounts for everything else in the ship not bolted down also flying 'up'? Did Volyova spend months cleaning up the mess? Is this an oversight?
