Dropoff, as a landscape designer myself such a conspicuous feature as the "eye" in the Danish assembly hall is never made by accident. The issue here is whether it was foisted on an unsuspecting Watchtower Society, as it was then called, by a cheeky architect or did they approve of or even give instructions for the design aware that the "eye" looks like the masonic symbol.
Remember they were still condemning the UN organisation at this time and yet had joined them as an NGO member.
My experience with the JW hierarchy is that they would not entertain anything which could be misinterpreted but at the same time they are likely to leave aesthetic judgements up to the designer or architect.
Oppostate, humans have been able to get off the ground since the days of the Montgolfier brothers.
