Sorry, but that's ridiculous. Over 300 people nearly died, and they're refusing to give their account of the situation and their insights/thinking at the time? I believe that it's quite frankly an insult to what the industry has been working towards - the highest level of safety possible. Don't most of us believe Just Culture? And so what if the interviews are recorded electronically? Nothing from the final report can be taken as liability nor can it be used to appoint blame. The basic question in this investigation that must be answered is: 'why did a 737 at a high speed almost crash into a 777?'. For the sake of the industry, you must have an openness and willing to be transparent in explaining from your perspective what happened in a particular instance. If you don't, then the result can end up with blood.
