Excuse me while I take a dump...

Sweet! Not his first try!

I think he forgot to raise the rollers up on the first try at 5-6 seconds. Then a guy runs up raises them at 16 seconds. Could be wrong, but that is what I see.

He did get them unloaded nicely. But, flexing the trusses sideways like that loosens all the nail plates holding them together and ruins the stuctural integrity of all of them.

Not as much as you would think, the plates used in commercially manufactured trusses are not the same junk that is sold to the unsuspecting consumers at the big box stores. The wood does most of the flexing, that and the trusses are engineered to meet some pretty strict standards all connecting materials has to undergo testing in all conditions if they weren't then if would be nearly impossible to install then without damaging

Having a construction official. sub code official and a building inspectors license, required attending five seminars in two years.
One morning on the way to the seminar, I passed a construction site installing trusses. The lesson for the day was proper bracing to prevent collapse.
When I passed the site on the way home I could tell the trusses were not braced properly. The next morning all of the installed trusses had fallen down!

I've seen that happen even on pre-engineered steel building construction sites, It doesn't mean a flying cow chip if something is engineered to support a D11 Cat dozer, if it is not properly braced chances are it cannot even support its own weight by itself let alone resist any wind
