We all were thinking with our hands yesterday, on the eve of the 50th year anniversary of the manned moon landing. It was very hot work. (More like working on a sungate)
Anyway,I think our stonework is beginning to reflect some of the momentousness of that historic occasion.
It seems however, in the pic (sent back from space) that everyone has their own idea of what the final upper trajectory of the curve of the moongate should be.
