    Really. Are they fighting wind? Or who's pushing on the other side of that wall?

    On 2nd thought, though, on a wall that tall, their lever arm – and leverage – from the fulcrum at the base, decreases the higher the wall gets. I ran into the same problem, with a very tall – and heavy – extension ladder, myself once. ( )

    This will help explain it

    Next in theaters "When you decide you do need a wall jack" Alt title "When do you decide..." The trailer previews at 0:41.

    Leaves me wondering who decided renting or buying jacks was out of budget. Not to mention what bunch of guys in tool belts don't know where to borrow a set? Another fail was not having one step off with a post to jack the across below ridge peak. Or tether the up side, hitched to a truck. Now guys; stay in step equidistant from the sill, or make the load on some exceed that on others.
    And roughed windows cut out hand holds for a third of the manpower; but two use left one as escape hatch. Buster Keaton, they are not.
    Go for help boys, find Lassie!

    Agreed on those windows changing the dynamic of the lift. Grey shirt guy 2nd from the right moves from the window header to a good spot. But the guys on the left don't have that option, and it makes the lift confusing.

    And, the second (yes, at 0:41) that the guy in black on the left decides to escape through the window, panic sets in, red shirt guy to his right follows his lead, and it's game over.

    Psychologists or social scientists could have a field day using this as an analogy for various different human group interactions.

    They didn't need to rent wall jacks. The simplest thing to do is cut a series or differing length boards to serve as stops as the wall was raised these boards would have been hinge bolted tot the wall frame while it was on the ground or blocked up a little so the boards would extend out from the frame as the frame was raised all of these would be dragged along the shortest would become vertical first becoming rest stops if needed as the wall could lay on them as the wall went up the successively longer boards would also drag to vertical eventually as the wall reached a certain angle of erection the longest boards would slide over stops or a fixed ladder laying on the ground anchored to the bottom of the wall once the wall was full vertical the long boards would be the bracing that held it upright boards on the opposite side could do the same thing in reverse instead of sliding up stops on the ground they would have a fixed pocket on the ground and slide to a prearranged stop on the outside of the wall.
    Even if they only got the wall 2/3rds of the way up on the first try it would rest there until they either had more guys or cought their breath for the final push.

    Jon is right. Psychologists and social scientists are great observers in hindsight. And the worst of labor apprentices.
