I saw people arguing that the explosion must have come from below (eg a boat) because parts of the damaged doad deck had been lifted off the spherical bearings of the supporting piers/pylons. Is it possible this could also be attributable to the 'tension load lifting the deck up'?
That’s also an important thing a lot of people don’t think of! The kinetics of lightweight materials in the vicinity of an event like an explosion or other violent events is quite surprising. It often masks the underlying prevailing forces because the more visible things obscure our view.
