Decisions
As a general statement, as we do not know the background to this particular incident.
I believe it is beholden on all of us professional and experienced pilots to say something when we see someone about to try and operate beyond their ability, but in practice very few people ever do.
Some years ago I was present when a PPL IMC chap was about to to try and take off to get home in a single engine piston 6 seater without any airframe anti or deicing equipment. The weather was freezing fog and stratus with embedded icing. Incredibly there were other professional pilots around who turned their back and hid by the coffee machine when I was trying to persuade this chap not to fly. They just kept quiet and did not want to get involved. I am still fairly confident that I prevented the chap from having an accident that day.
Please be prepared to help each other carefully and sensibly, even if it means sticking your neck out sometimes.
