The “dynamics” at play are pressure, not just water pressure with depth, but, the “boing” tension in the debris, including very sharp metal is present.
This is a deconstruction site, not a construction site. Normally construction sites are controlled by KNOWN dynamics of large pieces of steel and concrete. While accidents occur at construction sites, there is a degree of control that exists that does not exist with the collapsed Key Bridge.
The debris field of the Key Bridge is extremely large and within a fast flowing river. There are all kinds of fluid physics at play.
The people working in this debris field should be afforded all measures of safety simply because as the debris is moved high amounts of energy can be released with that movement. All that potential and kinetic and positional energy can cause deaths if mistaken judgement is made.
This is a highly dangerous work environment and the experts involved need to be fully in charge of all the work being conducted. To realize how dangerous this work area is, is to realize the degree of expertise brought to bear.
I wish everyone without exception the greatest degree of safety and success.
The deconstruction site can be a tourist attraction AT A SAFE DISTANCE as determined by the engineers involved. School children can marvel at the size of “the big cranes.” The workers can be glamorous people deserving admiration.
I have no doubt the loss of life will be a previous reality of the story if this bridge. It is history.
