Well, yeah as he says, if they had worn masks and/or socially distanced like normal people the incidence would have likely been much lower (in fact he says it was completely effective in the production staff). Wearing eye protection (even standard corrective eyeglasses) removes a significant secondary exposure mechanism. Certainly, there are hospital settings where doctors and nurses are around many highly infectious patients with regular high risk asperating events who do not become infected for many weeks or months. So it's not at all impossible it just takes effort and diligence. They are just viruses after all. I'd also say that they selected for who were less risk averse since those were the ones who showed up. And most of them flew and traversed public transport so really not that surprising they found what was likely a single superspreader.
