I want to know the answer to the following question:
What demonstrated equipment controlled by computers not connected to the internet can also be vulnerable?
All the background I'm provided with is that "The Internet is a potential attack vector for such machines if connected, but the Stuxnet worm demonstrated that even equipment controlled by computers not connected to the Internet can be vulnerable to physical damage caused by malicious commands sent to industrial equipment (in that case uranium enrichment centrifuges) which are infected via removable media.". Is that enough to answer the question?
Answer: yes
