SJ and David are aligned

Interesting how you worked that out...... The difference there id we say David is about 6ft would be nearly 9ft tall. Cant say the way you placed David is correct, but i did also compare David in the Orrey Room to the shots of the Engineers and kept getting back a height of about 9ft for them... Compared to David the Height of those tunnels would also apear to be about 10ft tall.

where'd that pic come from??? I haven't seen that yet...

Otto: I cant remember the source of pict I worked a little 3d programs so this is a simple perspective tech. Find out escape point by some straight lines passing thru points of parallel/perpendicular objects in photo. Then get interested object's upper/lower overlaping points on these lines and move them any coordinates along these lines. huh!.. in an earlier interview RS told that Engineers are about 9 ft so this may geometrically proves it

Would make more sense if you actually carried the field of view out beyond the photo
