Full respect for your depth and open-minded consideration Learner, but surely the concept of the flight crew relying on a gesture/s to signal something as fundamental as a radar return that could be an island, when at 200ft at night, is getting beyond the bounds of credibility? Given also that two other crew are in the back and supposed to be part of the team, surely too such an approach would be well outside SOPs, convention and common sense? The FLIR operator, who we think was the only one to detect Blackrock island (what should have been) early enough, clearly would have benefitted from being aware of any flight crew recognition of such a radar return - which would have presumably needed to be by voice.
