7/7/26 Manhattan Collapse Box 790

Pardon my ignorance but does a drone flying inside a building give the same answers they’re looking for compared to humans inspecting? Generally curious. I think it sounds the same as a “surround and drown” operation of a vacant but in this case maybe brief inspections by SOC before seeing how serious this is was necessary? Either way, you’re more experienced than I would be and it makes for good discussion.

You and I would call it experience or perhaps "street smarts". The proper concept is the German word "Gestalt"- looking at something as a whole rather than as a collection of separate parts. Humans do it, drones can't (so far).

I think the initial use of drones would be better to evaluate whether or not it was safe enough to put even one member on those floors to evaluate the situation. Worst case scenario - I'd rather chance losing two or three $50,000 drones than ONE member if even a partial collapse would occur.

The other 2 problems with drones, are size and signal. A building, especially under construction may block the signal the drone needs to operate. In which case it's useless. They typically need access to a.certain amount of satellites to operate effectively. The other problem is the size of the drone vs the space available. In some cases, the drone may be physically to big to maneuver around or tbrough obstacles like door frames, some hallways etc.
Another issues is the actual feel of the bldg. Walking thru a floor, a person may feel the floor spongy, or bowed, feel vibrations,hear the joints stressing or moving, or notice things a drone wouldn't. A drone can't open door which if it doesn't open normally is another clue something isn't right. Unfortunately this is one of those catch 22s.
