The relevant paragraph that summarizes the incident:
> Wang was the principal designer of an experiment called the Drop Dynamics Module, which aimed to uncover the fundamental physical behavior of liquid drops in microgravity.
> Despite his extensive preparation, the experiment malfunctioned upon activation. Wang, feeling immense pressure and aware of the high expectations from the Chinese community, became deeply despondent. When Wang's experiment failed, he desperately negotiated with NASA flight controllers for a chance to repair it, even threatening not to return if not allowed to fix the instrument, telling NASA flight controllers "Hey, if you guys don't give me a chance to repair my instrument, I'm not going back."
> Wang received permission to attempt a fix and was successful in repairing the experiment, though his remark caused concern for the safety of the crew and the mission.
