Factual error: When Ryan is in the ISS emergency capsule, she talks bi-directionally with the earth. But radio is a unidirectional technology where you have to push a button for talking or use a VOX technology. Simply talking both-ways like using a mobile phone is not possible. But she is talking while we can hear the remote voices. (00:55:30 - 00:56:22)
Factual error: When Ryan is undoing bolts with the tool she is turning them the wrong way meaning all the bolts must have been left hand thread which would not be normally the case. Also, when she closed a valve on the outside of the capsule she turned it the wrong way which would have been opening the valve.
Answer: If they had been tightly tethered to the space station, he would have bounced back toward her. But her foot was only tangled in parachute cords, so that when the tether snapped taught all it did was begin to pull her away from the station as the parachute cords gave more and more slack, slipping more and more loose as they drifted further away.
