You've inspected one bridge with a drone, you can inspect them all, right? If only that were true! Unfortunately for inspectors, engineers and architects have deployed multiple designs and materials in the building of bridges all over the world.

This is the story of one particular bridge in California that needed its O-rings inspected. The only problem? They were inside concrete pillars. Sky Ladder was called in by ConnexiCore to tackle the job. We spoke with Steven Katz, founder of Sky Ladder, about this challenging inspection and how they eventually were able to conquer the mission impossible bridge.
