Does anyone have any more insight into how this actually works logistically? I've been trying to figure it out and really only have some speculative guesses.
As far as I know, the trusses are all one piece correct? So how does it get staged below the launcher and between the two pilons and then get lifted into place when it is in fact longer than the distance between the two pilons- as presumably the go from center to center? Perhaps I'm wrong in believing that the truss is being lifted from below in the first place as opposed to slid into place from the eastern abuttment (in this particular case) seen in the pic.
